    Excitation of quadrupole vibrations in two-nucleon transfer reactions (1978)
    Springer
    The European physical journal 289 (1978), S. 83-87 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The spectroscopic factor is considered for two-nucleon transfer reactions involving the excitation of quadrupole one-phonon states. Special attention is payed to the number of particles conservation condition in the dynamically distorted average potential of the deforming nucleus. It is required that the mean square of the time-derivtive of the particle number operator is zero in the collective phonon state. The condition is satisfied by a specially chosen residual interaction terms.

    Energy- andN-averagings in the shell correction method (1979)
    Springer
    The European physical journal 293 (1979), S. 337-342 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    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.

    Semiclassical interpretation of the gross-shell structure in deformed nuclei (1977)
    Springer
    The European physical journal 283 (1977), S. 269-285 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract An analysis of the classical closed orbits in the infinitely deep elongated ellipsoidal well is given with respect to their relevance to the gross-shell structure of the single-particle spectra in deformed nuclei. It is shown that the deformed-shape gross-shells responsible for the ground state deformations, as well as those responsible for the fission intermediate states, find a reasonable explanation in terms of the semiclassical three-dimensional quantization involving the planar orbits in the axis-of-symmetry plane and the simplest three-dimensional orbits which appear at large distortions. The former are found important for the ground state shapes. The results are also compared with the harmonic oscillator model.

    Macroscopic rotation of cold nuclei (1978)

    Topics: Physics
    Notes: Abstract Using the statistical model, an estimate is obtained for the critical angular momentum when the rotational band ofγ-rays ends up in reactions with heavy ions. A model of classical non-quantized rotation is proposed for angular momenta exceeding the critical value. Estimates for the intensity ofγ-radiation and the descend time along the yrast-line proceeding the quantal rotation are given.

    Semi-classical approximation to the liquid-particle model (1985)

    Notes: Abstract Equation for the gas component of the density matrix, as defined for the nuclear volume in the Liquid-Particle Model, is related to Landau's zero-sound equation for a distribution function. Boundary conditions which determine the physical solution are deduced which are set at a certain effective sharp surface and couple the volume density vibrations to dynamics of diffused surface layer of the density.

    Superdeformed states in rotating152Dy (1987)

    Notes: Abstract The recently observed gamma-spectrum of152Dy at angular momenta 25〉~I〉~60 is interpreted in terms of a strongly deformed shape isomer. A pronounced minimum is found for these angular momenta in the sum of liquid-drop energy (including rotational part) and shell-correction (calculated in the Nilsson model) of152Dy. The general criteria for stability of this minimum against rotation are discussed.

    Notes: Abstract The cranking model calculation is analysed in the case of large amplitudes of collective motion and a finite velocity where the quantum perturbation theory is inapplicable.
