The 0+-spectrum in rare earth nuclei within the pseudo-SU(3) shell model
Peter O. Hess, Sahila Chopra
The study of the structure of the 0+ spectrum in heavy nuclei has drawn much attention in the last two decades. In this contribution we study their properties from a microscopic po…
Collective description of low energy mesonic states
Tochtli Yepez-Martinez, Octavio Rico Trejo, Peter Otto Hess +1
The phenomenology of hadronic states at high energy is well described in the framework of Quantum Chromodynamics. The theory, well established by now, cannot be applied to the desc…
Collective Modes of Tri-Nuclear Molecules
P. O. Hess, S. Misicu, W. Greiner +1
A geometrical model for tri-nuclear molecules is presented. An analytical solution is obtained provided the nuclei, which are taken to be prolately deformed, are connected in line…
Single- and double-beta decay Fermi-transitions in an exactly solvable model
Jorge G. Hirsch, Peter O. Hess, Osvaldo Civitarese
An exactly solvable model suitable for the description of single and double-beta decay processes of the Fermi-type is introduced. The model is equivalent to the exact shell-model t…
Renormalized QRPA and double beta decay: a critical analysis of double Fermi transitions
Jorge G. Hirsch, Peter O. Hess, Osvaldo Civitarese
The proton-neutron monopole Lipkin model, which exhibits some properties which are relevant for those double beta decay () transitions mediated by the Fermi matrix elements, is…
Double beta decay of : the deformed limit
Jorge G. Hirsch, O. Castaños, P. O. Hess +1
The double beta decay of to the ground state and excited states of is analysed in the context of the pseudo SU(3) scheme. The results of this deformed limit a…
Neutrinoless Double Beta Decay in Heavy Deformed Nuclei
Jorge G. Hirsch, O. Castaños, P. O. Hess
The zero neutrino mode of the double beta decay in heavy deformed nuclei is investigated in the framework of the pseudo SU(3) model, which has provided an accurate description of c…
