The common treatment of proton-neutron (pn) pairing in N = Z nuclei relies on Cooper pairs and HFB-type models. However, in these nuclei the pn interaction generates quartet correlations of alpha type which compete with the Cooper pairs. In fact, for any T=0 and T=1 pairing interactions the ground state of N = Z systems is accurately described not by Cooper pairs but in terms of collective...

The treatment of proton-neutron pairing in self-conjugate nuclei in terms of conventional BCS-type approaches has revealed to be problematic. We have shown [1-4] that this form of pairing can be very well accounted for in a formalism of $J=0,T=0$ quartets. We have extended the quartet formalism to the treatment of realistic interactions both in the case of even-even [5,6] and odd-odd [7]...

In order to investigate 212Po alpha-structure, the inverse kinematic thick target method has been used to study elastic and inelastic scattering of 208Pb on 4He target. A 208Pb beam produced by the Superconducting Cyclotron (CS), INFN-LNS, at the incident energy of 10 MeV/u was sent onto a 4He gas cell. The gas cell was acting as target and as beam degrader, completely stopping the beam...
