INC-SOURCE On its way to the collimators an unpolarized proton    F098900100012 
           beam is deflected in an auxiliary magnetic field by an F098900100013 
           angle of 14.2 degr. Thus the beam was purified of      F098900100014 
           neutral and low energy particle admixture.             F098900100015 
           Geometrically, the collimation was such that at the    F098900100016 
           place of the scatterer the following conditions were   F098900100017 
           fulfilled: a) the beam image on the autograph was 20 mmF098900100018 
           high and 10 mm wide and b) the horizontal plane beam   F098900100019 
           divergence was equal to +-0.15 degr. Due care was takenF098900100020 
           to reduce the proton scattering effect in the          F098900100021 
           collimator walls.                                      F098900100022 
DETECTOR   (TELES,SCIN,CEREN) The scattered protons were          F098900100023 
           registered by a telescope of 3 scintillation counters  F098900100024 
           and one Cerenkov counter with a plexiglass radiator.   F098900100025 
MONITOR    The averaged results of the measurements of the        F098900100026 
           counting rate were used to plot the angular            F098900100027 
           distribution of charged secondaries. The corresponding F098900100028 
           curve   was  then  normalized to  values of the        F098900100029 
           differential cross sections for the emission of        F098900100030 
           charged secondaries in p+C collisions, which were      F098900100031 
           obtained earlier in L.Azhgirey,J,JETP,36,1631,1959,    F098900100032 
           under conditions identical with those of the present   F098900100033 
           experiments. The total energy spectrum of charged      F098900100034 
           secondaries, measured at 7 degr., was also normalized  F098900100035 
           to a value of the differential cross section for       F098900100036 
           the same angles and equal to 1.1+-0.055 b/sr.          F098900100037
