摘要:

本文报道了动量从+/-3 GeV/c到+/-15 GeV/c的质子和π介子束与5%核相互作用长度厚的固定铅靶相互作用产生次级质子、带电π介子和氘核的双微分包容截面。结果给出的次级粒子与生产角20至125度。铅核的截面与铍、铜和钽核的截面进行了比较。

英文摘要:

We report on double-differential inclusive cross-sections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% nuclear interaction length thick stationary lead target, of proton and pion beams with momentum from +/-3 GeV/c to +/-15 GeV/c. Results are given for secondary particles with production angles 20 to 125 degrees. Cross-sections on lead nuclei are compared with cross-sections on beryllium, copper, and tantalum nuclei.
