    Notes: Abstract Energy shell corrections are derived for the nucleus238U by means of the new shell correction technique developed for finite depth single-particle potentials and exploiting only the bound states. The results are compared with those obtained by the traditional method.

    Energy- andN-averagings in the shell correction method (1979)
    Springer
    The European physical journal 293 (1979), S. 337-342 
    Details
    ISSN: 1434-601X

    Topics: Physics
    Notes: Abstract It is shown that a difference exists between the mean values of the total single-particle energies obtained by averaging over the nucleon numberN and over the phase-space distributions (the energy-averaging) due to the symmetry of the single-particle Hamiltonian. This difference could lead to significant corrections in fitting the nuclear masses involving the droplet model.

    Shell corrections for finite depth potentials. 3 (1984)

    Notes: Abstract The energy shell correction usually introduced in the traditional shell correction method is expressed in terms of quantities defined by the finite part of the single-particle spectrum. The dependence of the shell correction on the formal parameters of the theory is investigated and the best set of parameters is obtained. The numerical accuracy of the new prescription is high enough to calculate the deformation energy with realistic finite depth potentials. The relation between two types ofN-averaging used for extracting the smooth component of the energy is established.

    The adiabatic cranking model for large amplitudes (1989)
    Springer
    The European physical journal 334 (1989), S. 69-75

    Notes: Abstract A simple model of slow large scale collective nuclear motion is developed. Starting with the equation for the single-particle density matrix extended by approximate incorporation of particle collisions in the relaxation time approach the classical equation of motion for the collective variables specifying the shape of nuclear surface is derived. The coefficients of equation of motion are related to the microscopic quantities: single-particle energies, occupation numbers, derivatives of s.-p. energies with respect to the deformation parameters. The one- and two-body contributions to the collective mass and friction parameters are discussed.

    Towards a macroscopic generator coordinate method (1992)
    Springer
    The European physical journal 341 (1992), S. 267-274

    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.

    Shell corrections for finite depth potentials (1978)
    Springer
    The European physical journal 286 (1978), S. 291-297 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract An improved version of the shell correction method is suggested valid for use with finite depth potentials without referring to unbound part of the spectrum. The improved values for the shell corrections are quite stable with respect to the variation of free parameters. Comparison with earlier calculations is given.

    Towards CRAMOLA, the cranking model for large amplitudes (1982)
    Springer
    The European physical journal 306 (1982), S. 273-280 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Arguments are presented showing that the traditional cranking model derivations applied to cases of finite velocity face serious problem due to violation of the consistency between the density distribution and the assumed external potential. A dynamical zero-approximation function determined with the moving adiabatic basis states is suggested which may help to overcome this difficulty and be used in an expansion exploiting the incoherency of the strong-coupling matrix elements at the level crossings.
