Inclusive spectra and the angular distribution of protons emitted backwards in the interaction of 640 MeV protons with nuclei

The inclusive cross sections of protons emitted with energies from 60 to 145 MeV in the bombardment of 12C by 640 MeV protons have been measured for seven laboratory angles from 1050 to 1600. Under the same conditions proton spectra have been studied at 1400 by using Be, Al, Cu and Pb targets. The behaviour of the structure function Esigmasub(t)-1.dsigma/d3P at intermediate energies is discussed. (Auth.)
