Polarization effects in (3He, p) reactions on 3He and 7Li at 14 MeV

Proton polarization in the14N(3He, p)16O reaction near 10 MeV and reaction mechanisms

“…The target was 99.99 % pure N z at 400Torr confined in a gas cell covered with a continuous Havar foil 2.11 mg cm-2 thick. The routine of the measurements has been described elsewhere [4]. However, in the present reaction, the finite geometry with a gaseous target and a differential cross section having strong derivatives, results in instrumental asymmetries which require a numerical correction.…”

“…India the known uncertainties in absolute normalization associated with the transition amplitudes and cross sections in two-nucleon transfer reactions. We have performed a systematic study of the polarization of outgoing protons in two-nucleon transfer reactions induced by 3He projectiles in the 1 p shell [4,5], with a polarimetry facility consisting of two Si polarimeters and ancillary equipment [-6]. Existing evidence on the dominance of the deuteron transfer mechanism [7] was reinforced in the course of our work [8,9].…”
