The nucleus 6B is particle unbound, and so far no resonances have been observed in any reactions.
In 1989Gr06, the (π+,π-) pion double charge exchange reaction was studied on 6Li at E(π+)=180 and 240 MeV. α subsequent study was carried out at E(π+)=120, 180, 240 MeV by 2007Fo05. Results from either study are consistent with production of the final system in a multi-body phase-space with no evidence of contributions from a 6B resonance.
