摘要:

研究了不同入射中子动量下的反应$np \rightarrow np π^+ π^-$。结果表明,动量大于3GeV/c时的反应特征可用正则化$π$交换模型(OPER)描述。当动量低于3GeV/c时,需要额外使用一个重子交换(OBE)机制。

英文摘要:

The reaction $np \rightarrow np π^+ π^-$ was studied at the various momenta of incident neutrons. It was shown that the characteristics of the reaction at the momenta above 3 GeV/c could be described by the model of reggeized $π$ exchange (OPER). At the momenta below 3 GeV/c, it was necessary to use additionally the mechanism of one baryon exchange (OBE).
