Investigating Neutron-Proton Pairing insd-Shell Nuclei via (p,3He) and (3He,p) Transfer Reactions

In this work we have investigated neutron-proton pairing in self-conjugate nuclei in the 2s-1d shell by means of np transfer reactions. In particular, we aim to shed light on the existence of the isoscalar np pairing. The experiment was conducted at Grand Raiden high-resolution spectrometer (Research Center for Nuclear Physics, Osaka - Japan) by using ^3He and proton beams to perform systematic measurements of (p,^3He) pick-up and (^3He,p) stripping reactions. We have obtained the absolute differential cross sections for a wide range of angles and the ratio of cross sections populating to the lowest J^Π = 0^+, 1^+ states in the odd–odd N = Z nuclei. Preliminary experimental results are
