Studies of the (3He,t) reaction on 32S and 48Ca. — •J. H. Thies, H. Dohmann, E.-W. Grewe, and D. Frekers — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, 48149 Münster
We have performed a 32S(3He,t) experiment to probe the GT− distribution in 32Cl. The measurement was performed at RCNP in Osaka (Japan) using the 420 MeV 3He-beam and the high resolution WS Course beam line. An energy resolution of 70 keV was achieved. The character of the transition was identified by means of its angular distribution up to θlab=2.5o. The (3He,t) reaction is an alternative to the (p,n) reaction and therefore should give identical results. The 48Ca(3He,t)48Sc was earlier performed at RCNP in 2005.
The extracted GT− distribution in 32Cl and 48Ti were then compared to (p,n) measurements, performed by Anderson et al. at IUCF in 1985. The extracted GT− strength shows, that both reactions give identical results near q = 0.
