Description
Level structure of $^{8}$He has been studied in the reaction of stopped pion absorption by $^{11}$B nuclei $^{11}$B($\pi^{-}$,pd)X. The experiment was carried out at the LANL with a two-arm semiconductor spectrometer. The missing mass spectrum in the range 0 MeV < MM < 50 MeV has been described by the superposition of phase-space distributions and the six states of $^{8}$He. Parameters of these states have been compared with data of other experimental and theoretical works.
