Pairing and vibrational correlations in the higher Tamm-Dancoff approximation (HTDA) approach

Abstract : The higher Tamm-Dancoff Approximation (HTDA) is extended to include vibrational correlations with or without pairing correlations. The residual interaction in use is of the delta (in the T = 1 channel) plus multipolemultipole type. In this paper we have limited our study to the mere case of isoscalar quadrupole correlations. The approach is illustrated by the consideration of ground state and isoscalar giant quadrupole resonance properties in the 40Ca nucleus.
