In potential elastic scattering, what occurs to the neutron?

It loses all its kinetic energy to the nucleus.

It is acted on and scattered by short-range nuclear forces.

It emits a gamma ray.

It forms a compound nucleus with the target nucleus.

2 / 10

What type of scattering occurs when there is no energy transferred into nuclear excitation?

Inelastic Scattering

Compound Scattering

Radiative Capture

Elastic Scattering

3 / 10

What type of reaction involves the absorption of a fast neutron by a nucleus followed by the ejection of a proton?

Neutron-proton or n-p reactions

Radiative Capture reactions

Elastic Scattering reactions

Inelastic Scattering reactions

4 / 10

What is the net effect of a neutron scattering reaction?

The nucleus is left in an excited state.

It's as if the projectile neutron had merely "bounced off" the nucleus.

A proton is ejected from the nucleus.

A gamma ray is emitted from the nucleus.

5 / 10

In radiative capture, how does the compound nucleus decay to its ground state?

By gamma emission

By alpha emission

By neutron emission

By proton emission

6 / 10

What type of scattering results in the target nucleus being left in an excited state after neutron emission?

Radiative Capture

Particle Ejection

Elastic Scattering

Inelastic Scattering

7 / 10

In a particle ejection reaction, what may or may not exist after a new particle is ejected?

The remaining nucleus may or may not exist in an excited state.

The incident neutron always leaves the nucleus.

The original nucleus is always left in an excited state.

The compound nucleus always returns to the ground state.

8 / 10

What happens to 16N7 after neutron absorption?

Transforms into 17N7 by emitting a proton

Decays to 16O8 with a 7.13-second half-life by emitting a beta particle
