The yields of pi K-+(-), pK(-), and p pi (-) atoms in the reaction p +Al->,
atom + X at energies of 24, 70, 50 GeV and emission angles of theta (lab)
= 1 degrees -6 degrees are calculated from inclusive-production cross secti
ons for p, pi (+), pi (-), and K-. Estimates of these hadronic-atom yields
for a Ta target are also given. The inclusive-production cross sections for
p, pi (+), pi (-), and K- are obtained within the Lund model of string fra
gmentation. The accuracy of the calculations is estimated by comparing sing
le particle yields calculated by the Lund model and experimental yields of
particles in proton-nucleus interactions. (C) 2000 MAIK "Nauka/Interperiodi
