A study of nˉp in-flight annihilations is presented. The 4π invariant mass spectrum resulting from the analysis of the five-prong exclusive events, following the annihilation of ∼ (100–297) MeV/c nˉ, reveals, besides a large structure centred at ∼ 1500 MeV/c2, some evidences for a new state around 1660 MeV/c2.
