Feasibility of an experimental search for a resonance of a pion and a light nucleus

Abstract

A hypothesis is proposed herein, suggesting that a pion-nuclear resonance may be observed in the α + d → 6 Li(3.563) + π 0 reaction. The resonance has a πN N α structure, containing αN N and πN N subsystems. The former corresponds to the A = 6 isotriplet ( 6 He g.s. , 6 Li(3.563), 6 Be g.s. ), whereas the latter is a hypothetical N N -decoupled dibaryon. This resonance may be populated using the 7 Li(p, d) reaction.
