Nuclear reaction studies with exotic boron beams
Spectroscopic investigation, on exotic nuclei, performed in two different experiments with secondary radioactive boron beams are discussed. Spectroscopic factors for the 13B+n bound-states are obtained by measuring momentum distribution of the 13B residual nucleus from knockout reaction of the 14B beam at intermediate energy. The momentum distributions are measured in coincidence with the emited gamma-rays from the excited residual 13B nucleus allowing spin-parity assignment and partial cross section determination. In the other experiment, a deuteron transfer, ²H(8B,alpha)6Be, reaction with low energy 8B beam are used to search for resonances in the unbound 6Be nucleus. The ANC - Asymptotic Normalization Coefficient method are presented and astrophysical implications of these two experiments are discussed.
