We report measurements of the cross sections for production of ..pi../sup -/ mesons on the nuclei Be, Al, Cu, Ag, Ta, and Au at an angle theta=62 mrad in bombardment by protons with momenta 3.95, 6.7, and 9.7 GeV/c. An analysis is made of the behavior of the functions f/sub A/(p/sub ..pi../) = (E/p/sup 2/) dsigma/dpd..cap omega.. and R/sub A/(p/sub ..pi../) =p/sub A/(p/sub ..pi../)/rho/sub Be/(p/sub ..pi../) (where rho/sub A/= (sigma/sup i n//sub p A/)-/sup 1/f/sub A/(p/sub ..pi../)) as a function of the pion momentum for various A. Cross sections for the reactions pAl..--> pi../sup -/..., represented in the form of a function f/sub Al/(x) where x=p/sub ..pi..//p/sub ..pi..//sub max/, are compared for different initial proton momenta.
