4 / 10

What happens to 16N7 after neutron absorption?

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

Decays to 16O8 by emitting a gamma ray

Transforms into 17N7 by emitting a proton

5 / 10

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

Inelastic Scattering

Radiative Capture

Elastic Scattering

Particle Ejection

6 / 10

In potential elastic scattering, what occurs to the neutron?

It forms a compound nucleus with the target nucleus.

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

It emits a gamma ray.

It loses all its kinetic energy to the nucleus.

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

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

By alpha emission

By gamma emission

By neutron emission

By proton emission

9 / 10

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

Radiative Capture

Inelastic Scattering

Elastic Scattering

Compound Scattering

10 / 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 gamma ray is emitted from the nucleus.

A proton is ejected from the nucleus.
