New experimental studies of nuclear spin-isospin responses

Abstract

Possible directions of nuclear spin-isospin response studies are discussed. They includes i) light-ion induced charge exchange reaction studies in inverse-kinematics experiments with RI-beams, ii) studies with heavy-ion stable-beam induced charge exchange reactions, and iii) studies with RI-beam induced charge exchange reactions. Among them, RI-beam induced charge exchange reactions have unique properties which are missing in stable-beam induced reactions and can be used to reveal new aspects of spin-isospin responses in nuclei. Several experiments have been done and are planned with the SHARAQ spectrometer at RI Beam Factory, by utilizing the unique properties.
