Continuum Coupling and Pair Correlation in Weakly Bound Deformed Nuclei
The RI-beam facilities in the new generation will increase significantly the number of experimentally accessible nuclei, especially in medium and heavy mass regions. We may reach nuclei close to the neutron drip-line in the 10 ≤ Z ≤ 20 and N ≥ 20 region, where a bunch of deformed neutron-rich nuclei are expected1. This will provide us with a new opportunity to study interplay among the presence...
متن کاملContinuum effects for the mean-field and pairing properties of weakly bound nuclei
Continuum effects in the weakly bound nuclei close to the drip-line are investigated using the analytically soluble Pöschl-Teller-Ginocchio potential. Pairing correlations are studied within the Hartree-Fock-Bogoliubov method. We show that both resonant and non-resonant continuum phase space is active in creating the pairing field. The influence of positive-energy phase space is quantified in t...
متن کاملFusion suppression and sub-barrier breakup of weakly bound nuclei.
The mechanism for the large suppression of complete fusion in the 9Be+208Pb reaction has been investigated through measurement of sub-barrier breakup of 9Be. Excluding breakup through the 8Be ground state, whose lifetime is too long, a prompt breakup component remains, having sufficient probability to explain the observed suppression of complete fusion. This appears to be associated with intera...
متن کاملTransfer and breakup of light weakly-bound nuclei
We investigate the origin of the effects observed in the fusion cross section of light weakly bound nuclei, through a review of the most recent experimental and theoretical works. In particular we focus on the well-documented fusion suppression at energies just above the potential barrier. We show that, besides the couplings to the breakup process, effects due to the couplings to transfer need ...
متن کاملOptical potentials of halo and weakly bound nuclei
The optical potential of halo and weakly bound nuclei has a long range part due to the coupling to breakup that damps the elastic scattering angular distributions at all angles for which the effect of the nuclear interaction is felt. In charge exchange reactions leading to a final state with a halo nucleus, the surface potential is responsible for a strong reduction in the absolute cross sectio...
