The conservation of energy tells us that energy before the collision equals energy the comes out of the system after the collision. In the case of a stationary target nuclei and a neutron beam we have as our initial energy
Rest mass (E - mc2) of the nuclei and the particle in the beam.
Kinetic energy of the nuclei and the neutron projectile.
So the initial energy looks like
KEn + mn*c2 + KEnuc + mnuc*c2
We note that the initial KE of the stationary nucleus is zero and omit this term.
KEn + mn*c2 + mnuc*c2
Assuming neutron absorption (i.e. only 1 particle) all of the energies after the collision are described by
KEnuc_f + mnic_f*c2
Use the principle of conservation of energy to set the two equal to one another.
KEn + mn*c2 + mnuc*c2 = KEnuc_f + mnic_f*c2
Now solve for the final KE of the combined nuclei, KEnuc_f
KEnuc_f = (KEn + mn*c2 + mnuc*c2) - (mnic_f*c2)
This is the recoil energy.
To calculate the recoil energy of a daughter nucleus, you can use the conservation of momentum principle. The recoil energy can be determined using the equation 1/2 mv^2, where m is the mass of the daughter nucleus and v is its velocity. This velocity can be calculated by considering the momentum of the parent nucleus before decay and the momentum of the daughter nucleus after decay.

What is meant by recoil electron in compton scattering?
In Compton scattering, the recoil electron refers to the electron that is ejected from an atom due to the impact of a high-energy photon. This electron carries some of the energy and momentum of the incident photon, and its direction and energy are altered as a result of the scattering event. The recoil electron plays a crucial role in determining the overall energy distribution of the scattered photons.
What happens when an atom absorbs energy?
It is actually the nucleus of the atom that emits energy. The energy we can harness comes from fission or splitting of the nucleus of uranium235 or plutonium239. The nucleus splits into two parts which recoil and give up their kinetic energy as heat when they are stopped in the fuel, and there is also some energy from gamma rays at the same time. Basically in the process the final results of the fission have lost mass, and this appears as energy following the relation E = M x C2. Atoms can also emit energy as radioactivity, without fissioning. This can be alpha, beta, or gamma radiation. Alpha and beta are particles, so that the resulting nucleus is changed and there results a different element. Gamma is a penetrating ray in the electromagnetic spectrum and corresponds to a change in the energy state of the nucleus, but it remains the same element.
What is nuclear energy made from?
Nuclear energy is primarily made from the process of nuclear fission, where atoms are split to release a large amount of energy. This process typically uses uranium or plutonium as fuel. Heat produced from this reaction is converted into electricity through steam turbines.
Why can't an electron in a photoelectric effect event absorb more than one photon?
In the photoelectric effect, an electron absorbs one photon and gains energy to be ejected from the material. If an electron absorbed more than one photon, the excess energy would be lost as heat rather than contributing to the ejection of the electron, limiting the effectiveness of the photoelectric effect in generating a measurable current.
What allows the skin to bend without tearing apart?
The skin's flexibility and ability to bend without tearing apart is due to its structure, which includes layers of collagen and elastin fibers that provide strength and elasticity. These proteins allow the skin to stretch and recoil without sustaining damage.
How can calculate recoil velocity of gun?
The recoil velocity of a gun can be calculated using the principle of conservation of momentum. The formula to calculate the recoil velocity is: Recoil velocity = (mass of bullet * velocity of bullet) / mass of gun. This formula takes into account the mass of the bullet, the velocity of the bullet, and the mass of the gun.
Does recoil velocity answer involve in the calculation of final kinetic energy?
Whether you need it depends on the specific situation, but the recoil velocity does affect the total energy.
What ia a gun recoil spring?
Semi-automatic firearms, such as the 1911A1 pistol use a spring to help absorb some of the recoil energy, and use the energy to reload the pistol.
What happens when an atom emits?

Gamma is a penetrating ray in the electromagnetic spectrum and corresponds to a change in the energy state of the nucleus, but it remains the same element.
True or false the energy from nuclear fission is released as heat?
True. Nuclear fission is a process in which the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy in the form of heat and radiation.
What does a gun recoil spring do?
Typically a recoil spring absorbs SOME of the energy from a weapons recoil and also resets the firearm's components (chambering a round, hammer, etc...) to allow the firearm to be shot again.
Why Mossbauer effect is limited to low energy gamma rays?
The Mössbauer effect is limited to low-energy gamma rays because higher energy gamma rays would cause the whole crystal lattice to recoil, preventing the resonant absorption of the gamma ray by the nucleus. Low-energy gamma rays are needed to allow the nucleus to absorb the gamma ray without causing significant lattice vibration.
What energy is there when a ball bounces?
Basically 2 types of energy are involved, Kinetic and Potential energy. When the ball bounces the kinetic energy starts changing into potential energy or as commonly referred to as energy of recoil.

How do you measure gun recoil?
Recoil is measured in pounds or kilograms of force- over a measured period of time. How recoil is FELT is not only how hard a firearm pushes against you, but over what time interval. A push that builds up gradually will feel less than one that is quick and sharp. You will usually see it expressed as ft lbs- one foot lb is the energy of 1 lb dropping one foot. The recoil energy is most precisely measured with an electronic gauge.
What is the recoil of a 308?
assuming that you talking about a .308 Winchester or the 7.62 NATO round recoil is factor of pure physics the lighter the weapon the greater the free recoil (kick).the heavier the bullet the greater the kick. the higher the velocity the more kick.there are many factors involved in calculating the recoil of any firearm.what does the gun weigh ?what is the barrel length? what is the bullet weight? is the gun a bolt action or auto-matic ? is it gas or recoil operated ? does it have a recoil reducer of some type? how effective is this recoil reducer? knowing the interior ballistics of a cartridge is only the beginning of calculating the recoil and barrel flip of any firearm. in my observation over many years most .308 guns have recoil effect of between 7-15 foot pounds of free recoil energy.
What is a sentence with the word recoil?
She fired the gun, causing it to recoil sharply in her hands.
