Abstract

A study of up in-night annihilations is presented. The 4 pi invariant mass spectrum resulting from the analysis of the five-prong exclusive events, following the annihilation of similar to(100-297) MeV/c ($) over bar n, reveals, besides a large structure centred at similar to 1500 MeV/c(2), some evidences for a new state around 1660 MeV/c(2).
