Abstract
The collective pairing hamiltonian is obtained in the framework of the generator coordinate method in the gaussian overlap approximation with a slightly modified BCS function used as a generator function. The collective variable alpha, measuring the monopole moment of the pairing field, and the gauge transformation angle phi are chosen as generator coordinates. The vibrational ground states are calculated by diagonalisation of the collective pairing hamiltonian in the harmonic oscillator basis.
