An enlarged superfluid model of atomic nucleus

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The well-known superfluid model (or quasi-particle phonon nuclear model (QPNM) of atomic nucleus is enlarged by including an adequate four-nucleon effective interaction in addition to the pairing and long-range effective residual interactions. New experimental data can be explained without affecting those observable already described by the QPNM and in addition new features can be enumerated: 1) superfluidities of the neutron and proton systems may be generated by one another; 2) the phase structure is enriched by a new superfluid phase dominated by alpha-type correlations (ATC) and 3) superfluid isomers and their bands of elementary excitations are predicted. Unusual large two-nucleon and alpha transfer reactions cross-sections as well as some unusual large alpha-decay widths can be explained.
