Nonequilibrium phase transition to a time-dependent probability density for a model of charge-density waves
(American Institute of Physics Publising LLC, 1987)
A nonequilibrium phase transition to a stable time-periodic one-particle probability density is found in a modified Fukuyama-Lee model of charge-density waves. The classical single-phase model of Grüner, Zawadowski, and ...

Refractive or diffractive interpretation of heavy-ion elastic scattering
(American Physical Society, 1981)
A characteristic pattern frequently observed in the angular distribution of heavy-ion elastic scattering at moderate energies above the Coulomb barrier has been attributed either to a Fresnel diffraction or to a rainbow ...

Backbending of Dy isotopes described with the neutron-photon IBA plus two-quasiparticle model
(Elsevier, 1986)
The formalism of the neutron-photon interacting boson model, extended to include two-quasiparticle excitations, is used in a study of the high spin states of 154,156,158Dy isotropes. Good agreement is obtained between the ...

Direct versus sequential four-particle transfer in heavy ion collisions with superfluid nuclei: Sn+Sn reaction
(American Physical Society, 1988)
The direct transfer of four nucleons in reactions with superfluid systems is compared with the feeding of the same final channel by a successive transfer of correlated nucleon pairs. A quantitative analysis is carried out ...

Nuclear-structure dependence of the fusion cross section for heavy ions
(Elsevier, 1980)
The energy dependence of the fusion cross section and its maximum value are well predicted, for a wide range of nuclei and energies, by introducing information on the nuclear matter density distribution into a simple formula

A calculation of low-lying collective states in odd-even nuclei
(Elsevier, 1984)
We present results of a calculation of properties of low-lying collective quadrupole states in odd-even nuclei within the framework of the proton-neutron interacting boson-fermion model.

Quadrupole moments and E2 transitions in the O(6) limit of the IBM
(Elsevier, 1988)
Quadrupole moments and E2 transitions in the O(6) limit of the interacting boson model are studied within a formalism based on the intrinsic frame. We show that the values of these quantities for both ground- and β-bands ...

Simple estimates of excitation energy sharing between heavy and light fragments in heavy-ion reactions
(American Physical Society, 1985)
Qualitative arguments are used to estiamte the ratio of excitation energies between heavy and light fragments for asymmetric heavy-ion collisions. The value of this quantity is linked to the relative role played by inelastic ...
