Fixed particle number and angular momentum double-projected BCS wave functions
In this paper, a method for projecting the usual BCS states simultaneously onto the eigenstates of particle number and angular momentum is suggested. Fomenko's method of projection in the occupation number space, which leads to rapidly converging series, seems to be very suitable to a subsequent projection onto the eigenstates of angular momentum. For simplicity, the deformation is restricted to be axially symmetric, and general double-projection formulas are established in this case. Simple numerical model calculations using the adiabatic assumption, show that it is important to project the BCS states onto the particle-number eigenstates before computing the rotational spectrum and the moment of inertia.
