Holloway, L.E. Alverson, George Oscar 2011-06-29T14:31:29Z 2011-06-29T14:31:29Z 10000-01-01 1979 Dimuon production has been studied at 217 Gev/c in pi- -hydrogen and pi- -beryllium collisions with a multiparticle spectrometer to detect associated particles. Particular attention has. been paid to the PSI Gamma spectrum which shows an excess of events in the region 3.5 Gev. Attributing this to the presence of the X (~3. 5) states implies that 94±50% of psis are produced via radiative chi decay.
