The nuclide $^{238} Np$ requires 4.2 MeV for fission. To remove a neutron from this nuclide requires an energy expenditure of 5.0 MeV. Is fissionable by thermal neutrons?

The $^{237} Np$ is fissionable by thermal neutrons.

TABLE OF CONTENTS

Step 1: A concept and identification of given data:

The energy required for the fission of a nuclide varies with the number of the nucleon in the nuclide or the mass number of that nuclide.

The energy required for the fission of $^{238} Np$ is $E_{1} = 4.2 MeV$ .

The energy required for the fission of $^{237} Np$ is $E_{2} = 5 MeV$ .

Step 2: Whether Np-237 is fissionable by thermal neutrons:

The mass number of $^{238} Np$ is $^{237} Np$ and energy required for fission is 4.2 MeV. The mass number of $^{237} Np$ is 237 and energy required for fission is 5 Me V which is more than the energy required for fission of $^{238} Np$ so the $^{237} Np$ is fissionable by thermal neutrons.

Hence, the $^{237} Np$ is fissionable by thermal neutrons.
