Correlated EoM and Distributions for A=6 Nuclei

M. Tomaselli, T. Kühl, D. Ursescu +1

Energy spectra and electromagnetic transitions of nuclei are strongly depending from the correlations of the bound nucleons. Two particle correlations are responsible for the scatt…

Statistical hadronization of heavy quarks in ultra-relativistic nucleus-nucleus collisions

A. Andronic, P. Braun-Munzinger, K. Redlich +1

We present new results on the statistical hadronization of heavy quarks at SPS, RHIC and LHC energies. Several new aspects are considered, among them a separation of the collision…

Gamma-soft Analog of the Confined Beta-soft Rotor Model

D. Bonatsos, D. Lenis, N. Pietralla +1

A gamma-soft analog of the confined beta-soft (CBS) rotor model is developed, by using a gamma-independent displaced infinite well beta-potential in the Bohr Hamiltonian, for which…

The role of the continuum and the spurious 1- transitions in incoherent mu - e conversion rate calculations

P. Papakonstantinou, O. Civitarese, T. S. Kosmas +1

By using the Continuum RPA (CRPA) method, the incoherent transition strength of the exotic mu - e conversion in the 208Pb and 40Ca nuclei is investigated. The question whether exci…
