A partial level scheme for 237Np is shown to the right. Use this
scheme plus the relevant Nilsson diagram (on the following pages,
which has the parameter 𝜖2 for the deformation) for this question.
(a) (1 pt) State whether 237Np is deformed or spherical, and give
two reasons why you came to this conclusion, one based on the
experimental observations (level scheme) and another based on your
theoretical expectation for the shape of 237Np (b) (1 pt) The
ground state of 237Np is due to the odd proton occupying which
Nillson level? Briefly explain your reasoning. (c) (2 pts) what
Nillson level is occupied when the nucleus is in the 60, 103, 159
and 226 keV states?
