A hemispherical dome, C197800100013 chromium plated and polished, was placed over the C197800100014 crystal. C197800100015 METHOD (PHD) A record on the film was made of the deflection C197800100016 on an oscilloscope due to the pulses caused by 30.6 C197800100017 Mev protons elastically scattered at a small angle by C197800100018 a thin gold foil. The data for the scattering from Be, C197800100019 C, and Al were taken electronically. Eight scales C197800100020 were set at differing discriminator levels to form a C197800100021 seven channel pulse height analyzer with two volt C197800100022 windows for pulses in the neighborhood of 70 volts. C197800100023 For each observation, a pulse height analysis of this C197800100024 kind was made, and the inelastic events were thus C197800100025 separated from the elastic events.

C197801000005 ERR-ANALYS (DATA-ERR) Of the various sources of uncertainty in C197801000006 the above results i. e. the collected charge, the C197801000007 foil surface density, the foil composition, the C197801000008 geometry, the background counting rate, the C197801000009 statistics of counting, and the determination of the C197801000010 proper separation between the elastic and inelastic C197801000011 events; the last two mentioned are by far the most C197801000012 important. From the histograms, an estimate of the C197801000013 uncertainty in the separation of elastic from C197801000014 inelastic events was made. This estimate, combined C197801000015 with the total number of counts in the elastic peak, C197801000016 forms the basis for the uncertainties indicated for a C197801000017 number of points on each of the curves in Figures. C197801000018 The combined estimated uncertainty (probable error) C197801000019 ranges from 8% at small angles to 18% at some of the C197801000020 largest angles of scattering.
