Abstract
Abstract
A hypothesis is proposed herein, suggesting that a pion-nuclear resonance may be observed in the $\alpha+d\to{}^6\mathrm{Li}(3.563)+\pi^0$ reaction. The resonance has a $\pi NN\alpha$ structure, containing $\alpha NN$ and $\pi NN$ subsystems. The former corresponds to the $A=6$ isotriplet $^6\mathrm{He}_\text{g.s.}$, $^6\mathrm{Li}(3.563)$, $^6\mathrm{Be}_\text{g.s.}$, whereas the latter is a hypothetical $NN$-decoupled dibaryon. We propose an experiment to search for this resonance using the $^7\mathrm{Li}(p,d)$ reaction.
