Description

A new variation-iteration scheme is proposed for obtaining symmetry-preserving solutions of the ground state and low excited states of a superfluid system. Numerical calculations are made for a system of doubly degenerated levels under the action of pairing forces, and the results obtained agree very well with the exact ones. (orig.)
