摘要

The inclusive reactions pn implies psub(s)=x and pi exp + implies psub(s)+x at incident momentum of 195 GeV/c have been studied in an exposure of the Fermilab 30-in. deuterium filled bubble chamber to a mixed ( pi exp + ,p) beam. Analysing the t and M exp 2 dependence of our data within the framework of triple Regge models it is concluded that pion exchange yields a dominating contribution. Comparing our data with the pp results it is concluded that isoscalar Regge exchange ( omega ) is much larger than isovector (rho) Regge exchange. We observe significant leading pi exp - emission from the recoiling mass x, comparable to that observed in on-mass shell pi exp - p implies pi exp - experiments. This verifies our conclusions about pion exchange dominance in the above reactions. (Atomindex citation 09:413363)
