High-Resolution B(GT) studies with (3He,t) reactions.

It has been shown that the (3He,t) charge exchange reaction at intermediate energies, used at zero momentum transfer in combination with high-resolution magnetic spectrometers is a very powerful probe for Gamow-Teller strengths. Several N = Z nuclei such as 46V [1] or 50Mn [2] have been investigated. Recently ab-initio nuclear structure calculations have become possible for light nuclei. Thus experimental studies on light nuclei have become of great current interest [3]. We review previous results obtained in 11C with respect to nuclear structure aspects and the Hoyle state, and present some early results of a 9Be(3He,t)9B experiment carried out recently, pointing out the significance of high-resolution charge-exchange reactions and the investigation of Gamow-Teller strengths for the understanding of nuclear structure in light nuclei.
