How many nucleons from the target nucleus are involved in direct nuclear reactions?
What is the direction of product distribution in a direct nuclear reaction?
Which of these statements is NOT true about compound nucleus reactions?
Resonances are formed
The target nucleus absorbs energy and enters an excited state
The interaction time is longer than in a direct nuclear reaction
The energy of the incident particle is high
What is conserved in elastic scattering reactions?
Why can inelastic scattering be ignored in light nuclei?
Inelastic scattering can be ignored in light nuclei because the energy level of their first excites state is too high.
Which of these represents a radiative capture reaction?
What is the difference between radiative capture at small neutron flux and at high neutron flux?
Small neutron flux results in fewer interactions and lower capture probabilities.
Neutron capture reactions are responsible for:
Pu breeding in reactor fuel.
High burn up in reactor fuel.
The formation of many fission products.
Fission reactions.
Which of these equations is an example of a charged particle ejection?
X + n → Y + α
X + α → Y + n
X + n → Y + γ
X + n → Y + p
Which of these is an example of a primary source of neutrons?
Spontaneous fission of Cf-252
A Sb-Be neutron source
(γ,n) production of photoneutrons
An (α,n) neutron source
