RATE OF PI(-)-ATOM PRODUCTION IN HIGH-ENERGY COLLISIONS()PI()

Yields of pi(+)pi(-) atoms in the reaction pAl-->(pi(+)pi(-) atom)X at energies of 24, 70, 450, and 1000 GeV and emission angles theta(lab)= 1 degrees, 2 degrees, 3 degrees, 4 degrees, 5 degrees, and 6 degrees a re calculated from the inclusive cross sections for pi(+) and pi(-) pr oduction. The yields of pi(+)pi(-) atoms are estimated for Be, Cu, Ag, and Ta. The inclusive cross sections for pi(+) and pi(-) production a re obtained within the Lund model of string fragmentation. The accurac y of the calculation is estimated by comparing the yields of single pa rticles as given by the Lund model and experimental data on the yields in proton-nucleus interactions.
