Abstract
We search for deformed neutron-rich nuclei in which peaks with a considerab le amount of the Gamow-Teller (GT) strength (say, the order of B-GT=1 in un its of g(A)(2)/4 pi) may be present in the excitation energy below a few Me V. The study is based on the Skyrme-type Hartree-Fock calculation plus Tamm -Dancoff approximation or random phase approximation. In addition to known deformed rare-earth nuclei lying at the edge of the beta stability line, vi e suggest deformed nuclei with Z approximate to 40-46 and N approximate to 62-70, which may have an appreciable amount of GT strength at very low ener gy.
