The neutron spectroscopic factor S n of the 7He ground state is extracted from an R-matrix analysis of a recent measurement of the 7Li(d, 2He)7He reaction with good energy resolution. The width extracted from a deconvolution of the spectrum is Γ = 1

A search for the J(pi) = 1/2(-) spin-orbit partner of the J(pi) = 3/2(-) ground state in He-7 has been performed with the Li-7(d, He-2) charge-exchange reaction. The experimental results are incompatible with recent claims of such a state at very low

A new experimental approach to the famous problem of the anomalously slow Gamow-Teller (GT) transitions in the {beta} decay of the A = 14 multiplet is presented. The GT strength distributions to excited states in {sup 14}C and {sup 14}O was studied i

Two charge‐exchange reactions were performed at intermediate energies in order to investigate the Gamow‐Teller strength distribution starting from 14Ng.s. in β+ and β− directions: 14N(d,2He)14C and 14N(3He,t)14O. We describe here a few delica

Spin‐isospin (Gamow‐Teller) excitations in 64Cu and 64Co have been studied using (3He,t) and (d,2He) charge‐exchange reactions on 64Ni. As the isospin of the 64Ni ground‐state is T0=4, states with T=3, 4 and 5 in 64Cu are excited via the (3He
