    Perhaps this will help with the discussion.

    Quadrupole deformation - Moller Chart of Nuclides

    Is one familiar with nuclear quadrupole moment?

    Download this document - http://personal.ph.surrey.ac.uk/~phs1pr/lecture_notes/nuc_expt_phr03.pdf
    and look on page 40 or (43 of 225).

    The quadrupole moment measures deformation from purely spherical.
    An elongated shape (like an American footbal) has a postive quadupole moment.
    A squashed shape (like a pancake) has a negaive quadrupole moment.
