✦ Synopsis

An intermediate coupling calculation is performed for a nucleon confined to move in a. i =! orbit and coupled to a nuclear surface capable of performing quadrupole oscillations.

It is shown that each term in the hamiltonian commutes with a symplectic group of transformations. This feature is used to define a representation in which the hamiltonian matrix takes an especially simple form. It is possible to follow the tra.nsition from weak to strong coupling, at which there appear sets of rotational bands built on equidistant vibrational excitations. These rotational bands have some special features due to the y-instability of the problem.
