Title: Probing alpha-like correlations and proton-neutron pairing in self-conjugate nuclei
Abstract (english)
The scope of the project is to investigate the alpha-like correlations and
proton-neutron pairing in N=Z nuclei by using: (a) alpha transfer reactions;
(b) superallowed alpha decays of N=Z nuclei above 100Sn; (c) delayed alignment in
high-spin states of heavy N=Z nuclei. In addition, we intend to study the effects
of proton-neutron pairing correlations in the framework of the Quartet-Meson-Coupling
approach, which treats consistently the tensor and the spin-orbit interactions.
Abstract (româna)
Scopul proiectului este investigarea corelatiilor de tip alpha si a
interactiei de pairing proton-neutronice folosind: (a) reactii de transfer;
(b) dezintegrarea alpha de tip "superallowed", observata recent in nucleele
N=Z mai grele decit 100Sn; (c) fenomenul "delayed alignment", observat in unele
nuclee grele cu N=Z. In plus, se vor studia efectele corelatiilor de pairing
in cadrul modelului Quark-Meson-Coupling, ce ofera o descriere self-consistenta
a interactiei tensoriale si a interactiei spin-orbita.
