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

The original nucleus is always left in an excited state.

The incident neutron always leaves the nucleus.

The compound nucleus always returns to the ground state.

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

2 / 10

What is the decay product of Tritium (3H)?

Transformation into deuterium (2H)

Emission of a strong gamma ray

Emission of a very weak particle (0.02 Mev) and no gamma rays

Emission of a neutron and a gamma ray

3 / 10

In potential elastic scattering, what occurs to the neutron?

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

It loses all its kinetic energy to the nucleus.

It emits a gamma ray.

It forms a compound nucleus with the target nucleus.

4 / 10

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

Elastic Scattering

Inelastic Scattering

Radiative Capture

Particle Ejection

5 / 10

What is the net effect of a neutron scattering reaction?

A gamma ray is emitted from the nucleus.

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

A proton is ejected from the nucleus.

The nucleus is left in an excited state.

6 / 10

7 / 10

What happens to 16N7 after neutron absorption?

Transforms into 17N7 by emitting a proton

Decays to 16O8 by emitting a gamma ray
