Observation of a two-step Glauber process in a double charge exchange of π+ mesons by nuclei
Vorob'ev I. I., Novikov L. S.
A two-step Glauber process in a double charge exchange of charged particles was observed for the first time. The cross section of the process for π + mesons with a momentum of 2.9 GeV/c produced as a result of double charge exchange in a mixture of carbon and xenon nuclei ((Ay = 25) is equal to 26± 16 μЪ, consistent with the theoretical prediction.
