Response of light drip line nuclei to spin dependent operators - art. no. 064314

The response of light drip line nuclei to spin-isospin dependent fields is investigated, using the self-consistent Hartree-Fock plus the random-phase approximation with Skyrme interactions. Including simultaneously both the i soscalar and isovector spin correlation, the random-phase-approximation res ponse function is estimated in the coordinate space so as to take properly into account the continuum effect. The spin-orbit splitting, which plays an essential role in the spin-dependent response functions, is examined as a function of the mass number when we approach the drip Line nuclei. It is fo und that the calculated M1 peaks in C-8(6)2 and He-8(2)6 are much lower in energy than those expected from our knowledge of the beta-stable nucleus C- 12(6)6. [S0556-2813(99)02212-8].
