    Notes: Abstract A variational method is developed based on the Hartree-Fock approximation, but not restricted to a single Slater determinant trial space. The idea is to find a subspace of collective states which are strongly coupled to the ground state by providing a systematic technique to generate these basis states from a Hartree-Fock-like state. In the resulting basis space a residual diagonalization is easily performed. An application to a solvable model is made, both to justify and to investigate the structure of our approach.

    Liquefication and crystallization of cooled relativistic ion beams (1987)
    Springer
    The European physical journal 328 (1987), S. 247-251

    Notes: Abstract Properties of existing and planned cooled beams of intermediate energy ions are shown to be in the physical regime where a liquid or possibly a crystal may be formed. Thus these beams could provide a laboratory system for fundamental tests of many-body theory. An experimental test of the beam structure, involving scattering of laser light, is discussed. The experimental configuration used would provide continuously tunable coherent light over a wide frequency range when crystallization occurs.
