TITLE Angular Distribution of 30.6 MeV Protons Elastically C197800100003
Scattered by Be, C, and Al C197800100004

DETECTOR (SCIN) The detector for the elastically scattered C197800100010
protons was a 12 mm stilbene crystal cube cemented C197800100011
onto the type 5819 photomultiplier with a cement C197800100012
polystyrene dissolved in xylene. 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. C197800100026

STATUS (CURVE) Fig. 5, page 12. 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. C197801000021
COMMENT For each element for angles of scattering less than C197801000022
30 degrees, phi was set at 90 degrees, and the C197801000023
scattering was observed on both sides of the beam, C197801000024
Plus and Minus angles. For larger angles, phi was set C197801000025
at 45 degrees, and the observations were made on only C197801000026
one side of the beam. C197801000027
