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)⁹ B 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.
