   Abstract:
   The model of Haff and Wilets is used with constrained Hartree- Fock-Bogoliubov wave functions to calculate the mass parameter, B_Q, for quadrupole deformations by involving a simple ansatz in the variational procedure. The resulting equation has a similar form to the corresponding Hartree-Fock energy and contains the same Hamiltonian matrix elements. Numerical results, which are sensitive to the accuracy of the wave functions and numerical approximations, are obtained for ¹⁰⁸Rb. Relative to standard generator coordinate results they show a small lowering in the energy from the extra variational function, but a large increase in B_Q comparable to its original value
