Question

U-235 will undergo fission by
(a) low energy neutrons only
(b) high energy neutrons only
(c) medium energy neutrons
(d) low energy protons only​

Answer 1

Answer:

Option A : low energy neutrons.

but U - 238 has to be bombarded with fast or high energy neutrons.

Answer 2

Answer:

Option(a) low energy neutrons only is the correct answer.

What is U-235  fission?

• A U-235 nucleus immediately splits in half after taking in an additional neutron. Fission is the term for this action (see diagram below).
• A split U-235 nucleus releases two to three neutrons each time it divides. As a result, starting a chain reaction is possible.
• The process of nuclear fission involves the splitting of an atom's nucleus into two or more smaller nuclei.
• Even by the energetic standards of radioactive decay, the fission process releases a very high quantity of energy and frequently results in gamma photons.
• Fission is a type of nuclear transmutation because the daughter atoms that are created are different elements from the parent atom.
• For typical fissile isotopes, the mass ratio of the two (or more) generated nuclei is normally about 3 to 2, with the two (or more) nuclei being of similar but slightly different sizes.
