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 ...

Accumulation of Poly(beta-Hydroxybutyrate) by Halobacteria
(American Society for Microbiology, 1986)
Some species of extremely halophilic archaebacteria, Halobacteriaceae, have been shown to accumulate large amounts of poly(P-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source. The production ...

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 ...

Approximation axiomatique à la théorie du bordisme
(Université de Picardie Jules Verne, 1989)
This paper gives an axiomatical approximation to Bordism Theory. It proves those properties of a geometrical nature that a class of models must satisfy to develop a bordism theory in an abstract category.

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, ...

Exponential law for uniformly continous proper maps
(Universitat Autònoma de Barcelona, 1988)
The purpose of this note is to prove the exponential law for uniformly continuous proper maps.

An Easy Method for the Determination of Ra Isotopes and Actinide Alpha Emitters from the Same Water Sample
(Elsevier, 1986)
Radium isotopes and actinide α emitters are easily determined from the same water sample. The Ra fraction is obtained by coprecipitation with Ba, while a Fe coprecipitation is used for the actinides. Both fractions are ...

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 ...
