从NN..-->；pi..d和Nn.-->；..NN..pi过程的数据中提取了产生NN单皮介子的同位旋反应截面。新的数据结合旧的现有数据精确地确定了同位旋一(Pp)初始态的截面分量。其他关于NP初始态的新数据和对一些旧数据的正确处理表明，1000 MeV以下的同位旋零反应截面基本上为零，这表明不存在非弹性同位旋零NN共振。
The isospin reaction cross sections for NN single pion production are extracted from data for the processes NN..--> pi..d and NN..-->..NN..pi... New data in conjunction with older existing data have precisely determined the components of the cross sections for the isospin one (pp) initial state. Other new data for the np initial state and correct treatment of some older data indicate that the isospin zero reaction cross section is essentially zero below 1000 MeV, which indicates against the presence of inelastic isospin zero NN resonances.
