Description of Heavy Quark Systems by means of Energy Dependent Potentials
R. J. Lombard, J. Mares, C. Volpe
We apply, for the first time, an energy dependent Schrodinger equation to describe static properties of heavy quark systems, i.e. charmonium and bottonium. We show that a good desc…
Critical strength of attractive central potentials
Fabian Brau, Monique Lassaut
We obtain several sequences of necessary and sufficient conditions for the existence of bound states applicable to attractive (purely negative) central potentials. These conditions…
Cluster excitation and ionization in high velocity collisions:the atomic approach
Ferid Mezdari, Karine Wohrer-Beroff, Marin Chabot
The independent atom and electron model [1] is introduced in a quantum context and associated approximations tentatively estimated. Confrontation of the model to measured ionizatio…
Second virial coefficient in one dimension, as a function of asymptotic quantities
A. Amaya-Tapia, S. Y. Larsen, M. Lassaut
A result from Dodd and Gibbs[1] for the second virial coefficient of particles in 1 dimension, subject to delta-function interactions, has been obtained by direct integration of th…
Seniority scenario for the 68-72Zn and 66-68Ni B(E2)^ difference
Isabelle Deloncle, Brigitte Roussiere
The very simple product of the number of particles by the number of holes appearing in the expression of the reduced B(E2: 0+1 -> 2+1) (B(E2)^) transition probability of even-even…
Model-independent tracking of criticality signals in nuclear multifragmentation data
J. D. Frankland, A. Chbihi, A. Mignon +41
We look for signals of criticality in multifragment production in heavy-ion collisions using model-independent universal fluctuations theory. The phenomenon is studied as a functio…
