Abstract
We investigate the momentum and angular characteristics (average momentum, emission angle, transverse momentum, and rapidity) of negative pions produced in interactions of deuterium, helium, and carbon nuclei with tantalum nuclei (A = 181) at a primary projectile-nucleus momentum p/sub 0/ = 4.2 GeV/c per nucleon, as functions of the variable that characterized the cumulative number. The results are compared with nucleon-nucleon data at the corresponding primary energy and with the predictions of the cascade model. We investigate also the behavior of the invariant differential cross section for ..pi../sup -/ meson production as functions of the cumulative number.
