Ground state energy fluctuations in the Nuclear Shell Model
Victor Velazquez, Jorge G. Hirsch, Alejandro Frank +2
Statistical fluctuations of the nuclear ground state energies are estimated using shell model calculations in which particles in the valence shells interact through well defined fo…
Nuclear masses set bounds on quantum chaos
Jose Barea, Alejandro Frank, Jorge G. Hirsch +1
It has been suggested that chaotic motion inside the nucleus may significantly limit the accuracy with which nuclear masses can be calculated. Using a power spectrum analysis we sh…
Two-nucleon transfer reactions uphold supersymmetry in atomic nuclei
J. Barea, R. Bijker, A. Frank
The spectroscopic strengths of two-nucleon transfer reactions constitute a stringent test for two-nucleon correlations in the nuclear wave functions. A comparison between the recen…
New correlations induced by nuclear supersymmetry
J. Barea, R. Bijker, A. Frank
We show that the nuclear supersymmetry model (n-susy) in its extended version, predicts correlations in the nuclear structure matrix elements which characterize transfer reactions…
A new look at nuclear supersymmetry though transfer experiments
J. Barea, R. Bijker, A. Frank
Nuclear supersymmetry is reviewed and some of its applications and extensions are discussed, together with a proposal for new, more stringent and precise tests to probe the supersy…
