Abstract
We have measured the spectra of double charged particles emitted in interaction of 3.6 GeV/nucleon ..cap alpha.. particles with lead nuclei. Spectra were measured at emission angles from 10 to 95/sup 0/ in the range of secondary-particle velocities 0.37<..beta..<0.55. Angular distributions were obtained, the total cross section for emission of doubly charged particles was evaluated, and the ratios of the contributions of doubly and singly charged particles were determined. The rapidity distributions of the invariant cross sections for production of doubly charged particles reveal maxima at a rapidity yroughly-equal0.15--0.20.
