Diproton decay of nuclei on the proton drip line.
The process of direct two-proton decay of nuclei with Z 22-28 on the proton drip line is considered. On the basis of new Od3t2 Offi2 -shell-model mass extrapolations, '9Ti, 42Cr, 45Fe, Ni, and Ni are found to be bound to single-proton decay but unbound to two-proton decay. New estimates of the spectroscopic factors and lifetimes have been made. The decays of Ti, Fe, and Ni are found to be promi...
متن کاملShape and shell-structure of nuclei towards neutron drip line
In nuclei along the β stability line the nucleons are bound at least by 7–10MeV, and the magic numbers in those nuclei are well known as N (or Z) = 8, 20, 28, 50, 82, and 126. In contrast, in nuclei away from the β stability line the presence of nucleons with binding energy much smaller than 8MeV leads to a unique shell-structure. Consequently, magic numbers may be changed and the nuclei, which...
متن کاملSub-barrier Fusion of Drip-line Nuclei
We discuss the role of break-up process of a loosely-bound projectile in subbarrier fusion reactions. Coupled-channels calculations are carried out for Be + Pb and 4,6He + U reactions by discretizing in energy the particle continuum states. Our calculations show that the coupling to the break-up channel has two effects, namely the loss of flux and the dynamical modulation of fusion potential. T...
متن کامل1 Nuclei beyond the drip line
In a Thomas-Fermi model, calculations are presented for nuclei beyond the nuclear drip line at zero temperature. These nuclei are in equilibrium by the presence of an external gas, as may be envisaged in the astrophysical scenario. We find that there is a limiting asymmetry beyond which these nuclei can no longer be made stable.
متن کاملMean-field description of ground-state properties of drip-line nuclei: Pairing and continuum effects.
Ground-state properties of exotic even-even nuclei with extreme neutron-to-proton ratios are described in the framework of the self-consistent mean-field theory with pairing formulated in coordinate space. This theory properly accounts for the influence of the particle continuum, which is particularly important for weakly bound systems. The pairing properties of nuclei far from stability are st...
