Etude des réactions²⁰Ne(t, p)²²Ne et²¹Ne(t, d)²²Ne àE t=3 et 3.4 mev

Absolute differential cross-sections were measured for proton groups from the20Ne(t, p)22Ne reaction at 3 and 3.4 MeV and for two deuteron groups from the21Ne(t, d)22Ne reaction at 3 MeV with a gas cell containing20Ne or21Ne. The total cross-sections of most groups were analysed in terms of Hauser-Feshbach theory and several final-state spin predictions are made. The angular distribution of the20Ne(t, p)22Ne (E x=6.24 MeV) reaction was analysed by double-stripping DWBA theory and indicates 0+ for this state, the isobaric analogue of which has been identified at 6.83 MeV in22Na. © 1975 Società Italiana di Fisica.
