- Title
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 |$\alpha+d\to{}^6\mathrm{Li}(3.563)+\pi^0$| 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.
