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 ...

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 information obtained from charge radii
(Elsevier, 1985)
We analyze the nuclear structure information obtained from measurements of charge radii in even-even and even-odd nuclei terms of the interacting boson model. The observed deviations from the smooth behavior, R = R0A1 3, ...

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 ...

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 ...

Test of the proton-neutron interacting boson-fermion model in the region around A=190
(American Physical Society, 1986)
We present systematic calculations on nuclei in the region around A=190 within the framework of the proton-neutron interacting boson-fermion model. Energy levels and electromagnetic properties of both positive and negative ...
