²³⁵U Is Readily Made Fissionable by a Thermal Neutron but ²³⁸U

question 38

Multiple Choice

²³⁵U is readily made fissionable by a thermal neutron but ²³⁸U is not because:

• A)the neutron has a smaller binding energy in ²³⁶U
• B)the neutron has a smaller excitation energy in ²³⁶U
• C)the potential barrier for the fragments is less in ²³⁹U
• D)the neutron binding energy is greater than the barrier height for ²³⁶U and less than the barrier height for ²³⁹U
• E)the neutron binding energy is less than the barrier height for ²³⁶U and greater than the barrier height for ²³⁹U
