Abstract
The β-decay of 36Ca has been studied at the projectile fragment separator at GSI Darmstadt. The measured Gamow-Teller strength function B (GT), deduced from the observed β-delayed proton- and γ-emission and from the measured half-life of 102(2) ms, is compared to results obtained from large-scale sd-shell model calculations. A systematic underestimation of the measured strength by the theory is found.

between experiment and shell-model predictions discussed in this letter, it will be useful to compare the 36Ca P-decay results from this work to those from future s6S(p,n) “VI or s6S( Q-le, t) %i experiments. Furthermore, 36S(n,p) or “6S(t,3He) data could provide information on the importance of higher-order shell model configurations because the GT strength in these reactions vanishes in the (2sld)” approximation. In addition it would be very interesting to have high-resolution, high-sensitivity delayed proton data on “%a decay which would probably uncover still more GT strength at high excitation energies, E.G.A. thanks CERN for support as a Faid Scientific Associate, Z.J. acknowledges support from the Alexander von Humboldt Foundation, and B.A.B. ac-knowlejges support from NSF grant 94-03566.
