Another way of improving the equations is to regard the U in (2) and (4) as differing from the special value of the < I> equation by a small quantity g (p). which goes to zero if the equivalent mass M is imagined to increase indefinitely. If (3) is the special value, the effect of the small quantity is to multiply all its constants by factors of the form (1 + ck2) and to add a blank term and a % term, each of order &k3. In consequence, all the constants such as B0, co0, ato0, a , .... are multiplied by factors of the form (1 + ck2). Again in what follows the generalisation is easily made.

A measurement of the energy and spin of superdeformed states in 190Hg, obtained through the observation of transitions directly linking superdeformed and normal states, expands the number of isotopes in which binding energies at superdeformation are known. Comparison with neighboring nuclei shows that two-proton separation energies are higher in the superdeformed state than in the normal state, despite the lower Coulomb barrier and lower total binding energy. This unexpected result provides a critical test for nuclear models.
