When a Fast Neutron Collides with a Hydrogen or Deuterium

question 34

Multiple Choice

When a fast neutron collides with a hydrogen or deuterium nucleus, the most likely result is that

• A) the neutron has an appreciable gain in kinetic energy, the gain being greatest for head-on collisions.
• B) the neutron has an appreciable gain in kinetic energy, the gain being greatest for oblique collisions.
• C) the neutron has an appreciable loss in kinetic energy, the loss being greatest for head-on collisions.
• D) the neutron has an appreciable loss in kinetic energy, the loss being greatest for oblique collisions.
• E) the neutron is absorbed by the hydrogen or deuterium nucleus.
