Recently O'Ceallalghl ) has found m the cosmic ray a new heavy meson (x-meson), which seems todistntegrate mto one charged J.I-meson and one or more neutral particles_ He also has found the lifetime of a new particle IS about 10-9 .sec.As the experimental facts seem to indicate us that x-meson distntegrates at least into three seccndary particles, we assume tentatively a following decay mode tor the x-meson.X±_>J.I± +N+N->J.I± +no+NI +N-.J.I± +no+ nO,
