FUN 1 EO: 1.12

1 / 10

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

Radiative Capture

Elastic Scattering

Inelastic Scattering

Particle Ejection

2 / 10

What is the net effect of a neutron scattering reaction?

A proton is ejected from the nucleus.

A gamma ray is emitted from the nucleus.

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

The nucleus is left in an excited state.

3 / 10

In potential elastic scattering, what occurs to the neutron?

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.

It forms a compound nucleus with the target nucleus.

4 / 10

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

The compound nucleus always returns to the ground state.

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.

5 / 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

Elastic Scattering reactions

Inelastic Scattering reactions

Neutron-proton or n-p reactions

6 / 10

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

Compound Scattering

Inelastic Scattering

Radiative Capture

Elastic Scattering

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 long half-life of these isotopes

The significant chemical effect on reactor coolant

8 / 10

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

Emission of a neutron and a gamma ray

Emission of a strong gamma ray

Transformation into deuterium (2H)

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

9 / 10

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

By neutron emission

By alpha emission

By gamma emission

By proton emission

10 / 10

What happens to 16N7 after neutron absorption?

Remains stable without any decay

Transforms into 17N7 by emitting a proton

Decays to 16O8 by emitting a gamma ray

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