1 / 10

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

Compound Scattering

Inelastic Scattering

Radiative Capture

Elastic Scattering

2 / 10

What happens to 16N7 after neutron absorption?

Decays to 16O8 by emitting a gamma ray

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

Remains stable without any decay

Transforms into 17N7 by emitting a proton

3 / 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 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.

4 / 10

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

Radiative Capture reactions

Neutron-proton or n-p reactions

Inelastic Scattering reactions

Elastic Scattering reactions

5 / 10

In potential elastic scattering, what occurs to the neutron?

It forms a compound nucleus with the target nucleus.

It emits a gamma ray.

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

It loses all its kinetic energy to the nucleus.

6 / 10

What is the net effect of a neutron scattering reaction?

A gamma ray is emitted from the nucleus.

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.

7 / 10

What is the main consideration in the design of shielding for nuclear facilities concerning the reactions 16O8 (n, p) 16N7 and 17O8 (n, p) 17N7?

The neutrons and high-energy gamma rays emitted by these isotopes

The absorption of alpha particles

The significant chemical effect on reactor coolant

The long half-life of these isotopes

8 / 10

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

By gamma emission

By proton emission

By neutron emission

By alpha emission

9 / 10

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

Emission of a neutron and a gamma ray

Emission of a strong gamma ray

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

Transformation into deuterium (2H)

10 / 10
