Spin-longitudinal and spin-transverse cross sections for Δ production in the reaction

We present ( p , n ) spin observable measurements in the delta region of excitation taken on the targets 2H and 12C at 0° and 795 MeV proton energy. These observables have been used to form the spin-longitudinal and spin-transverse cross sections. Good agreement is found between experiment and theory in the spin-longitudinal channel.
