Abstract

Pion pair production from the reaction p+Ta{yields}{pi}{sup +}+{pi}{sup -}+X at proton energy 70 GeV has been studied. Pions in the 0.8-2.4 GeV/c momentum range have been detected at an angle of 8.4{sup 0} to the proton beam, in acceptance angle of 3.8 sr. Pion pair correlations as a function of the relative momentum q in a {pi}{sup +}{pi}{sup -}-pair C.M.S. have been measured at the unstudied before region of q<40 MeV/c. The correlation function is observed sharply increasing at q reduction smaller than 10 MeV/c. The experimental data agree with the calculation that takes into account the Coulomb factor in the differential cross section of pion pairs production. 28 refs.; 11 figs.
