Abstract

Two and three particles coincidences of 11Bisotope and unidentified particles from 9Be + 13C collisions at energy E(9Be) = 89 MeV are analyzed as three particles exit  9Be + 13C → 11B + α + 7Li and four particles exit 9Be + 13C → 11B + α + α + τ channel. In spectrum of 7Li- α and α + α + τ relative energy 11B well-known states with Ex(11B)  = 8.9, 9.1, 9.3 and with  Ex(11B)  =11.14, 11.86, 12.2, 12.6, ~14.5, 19.7 are identified correspondingly. Also for the current processes are observed previously unregistered peaks (8.77 and ~20.2) which require further clarification.
