6Li(p,Δ++)6He reaction reanalysed

Using our recently developed formalism for the (p,Δ) reaction, which includes the decay of Δ inside the nuclear medium, we study the 6Li(p,Δ++)6He reaction, and compare the calculated cross sections with those measured some time back at Saturne. In the formalism, the Δ resonance decays into pπ+ either inside or outside the nuclear medium. The medium effects on Δ as well as on p and π+ are incorporated through appropriate optical potentials. The transition potential for the elementary process pp→nΔ++ is taken to be one pion-exchange, whose parameters are constrained to reproduce the measured spin averaged cross sections on the pp→ nΔ++ reaction over a large energy range. The calculated results agree well with the measured cross sections.
