B)0.4 eV
C)3 eV
D)100 eV
E)0.04 MeV

Question

Quizplus · Accepted Answer

Thermal neutrons have energies on the order of 0.025-0.5 eV, with 0.03 eV being a commonly used value. Therefore, choice A is the most characteristic energy value for a thermal neutron. The other choices are too high for thermal neutron energies.
