    Towards a macroscopic generator coordinate method (1992)

    Notes: Abstract Collective quantities are defined as macroscopic statistical averages over many level crossing points where microscopic densities are redistributed. Accordingly, the generator coordinate method (GCM) is reconsidered. It is concluded that, contrary to earlier arguments, the macroscopically defined inertia parameter which appears in the GCM Hamiltonian has a finite value close to that obtained using traditional theories assuming the existence of the adiabatic BCS ground state.

    Random-phase approximation as a macroscopic description (1990)
    Springer
    The European physical journal 336 (1990), S. 253-258

    Notes: Abstract Analysis of nuclear processes in terms of cross-sections averaged over the many microscopic channels, as in the “poor resolution” experiments, corresponds to a macroscopic level of description. In this paper energy-averaged strength function is considered. In order to determine the frequency dependence of this quantity statistically averaged single-particle density is introduced for which equations are obtained analogous to random phase approximation.
