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 ...

Double folding with a density-dependent effective interaction and its analytical approximation
(American Physical Society, 1981)
The real part of the optical potential for heavy ion elastic scattering is obtained by double folding of the nuclear densities with a density-dependent nucleon-nucleon effective interaction which was successful in describing ...

Polarization effects due to coupling of elastic to compound states
(Elsevier, 1987)
From a compound nucleus level-density-dependent imaginary potential an energy-and angular-momentum-dependent polarization potential is obtained by using the dispersion relation. The effect of coupling in this way the ...

Dispersive contribution to the nucleus-nucleus potential
(American Physical Society, 1987)
With a simple parametrization of the empirical imaginary potential depths, the real potential induced by a dispersion relation is calculated analytically for the elastic scattering of O16 by several target nuclei. Between ...

Effect of elastic transfer in sub-barrier fusion between similar nuclei
(American Physical Society, 1987)
We study the effect of the elastic transfer process on sub-barrier fusion reactions between similar nuclei. The coupling to the elastic transfer channel is described in terms of a parity dependent potential, directly ...

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 phenomenological imaginary part of the optical potential for heavy ions
(Elsevier, 1983)
The depth of the imaginary part of the optical potential is derived from the assumption that, at a given energy and for each partial wave L, it is proportional to the compound nucleus density level up to a given excitation ...

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 ...

The role of rainbow refraction in heavy ion elastic scattering
(Elsevier, 1980)
The energy dependence of both the strong absorption radius, Rsa, and the rainbow distance, Rr, in the elastic scattering of a dozen pairs of heavy ions is studied. Rsa decreases with energy linearly in E−13 while Rr increases ...
