Survey of the (α,He2) reaction on1p- and2s1d-shell nuclei

Abstract
A He2 detection system has been developed and used to investigate the (α, He2) reaction at bombarding energies of 55 and 65 MeV on targets of C12, C13, N14, N15, O16, O18, Ne20, Ne22, Mg24, Mg26, Si28, Si29, S32, Ar36, Ar38, and Ca40. Preferential population of two-neutron states with dominant (d52)24, (d32f72)5, and (f72)26 character was observed. A linear
