Study of Inelastic D + C sub 3 H sub 8 Interactions at Psub(D) = 4.6, 8.2 and 10 GeV/C Accompanied by the Emission of Secondary Deuteron with Momentum Larger Than Psub(D)/2

摘要

Inelastic d+C sub 3 H sub 8 interactions with secondary positive particle in the superstripping momentum region have been selected using pictures from a 2m propane bubble chamber exposed to 4.6, 8.2 and 10 GeV/c deuterons. Among these particles deuterons amount to (100sub(-20)sup(+0))%. For 375 events selected a peak is observed having an average mass of 2.90 GeV in the effective mass spectrum of dp combinations at all momentum values of primary deuterons. The width of the peak observed is 100 MeV. The number of events in the peak corresponds to the cross sections: sigma=(2+-1) mb at Psub(d)=4.6 GeV/c, sigma=(5+-1.5) mb at Psub(d)=8.2 GeV/c and sigma=(8+-2.5) mb at Psub(d)=10 GeV/c.
