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 ...

Isothermal molecular-dynamics calculations
(American Institute of Physics Publising LLC, 1985)
We have performed long-time runs of molecular-dynamics computer simulations of a two-dimensional Lennard-Jones system, without any scaling procedure. The thermodynamic properties show spontaneous fluctuations except when ...

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 ...

About the numerical solution of the Percus–Yevick equation in the critical region for nontruncated potentials
(AIP Publishing, 1983-07)
Some problems related to the numerical solution of the Percus–Yevick equation in the critical region for a nontruncated potential are discussed. It is shown that the numerical method employed by the authors in a previous ...

Valoración de la contaminación de neutrones producidos por un acelerador lineal de electrones (18 MV) de uso clínico
(1987)
Los haces de radiación de altas energías ( 10 MEV) están generalmente contaminados con neutrones resultantes de la reacción (y n) producida por la interacción de los fotones con los elementos constituyentes del acelerador ...

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.

Coupled channel effects in the scattering of 6,7Li BY 58Ni
(Elsevier, 1985)
Using a single-particle description of 6,7Li and Woods-Saxon generated wavefunctions for 58Ni matter density distribution, the diagonal and transition densities are calculated. Folding these densities with the M3Y effective ...
