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 or 50Mn 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. 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.
