SAMPLE Liquid argon. C196200100010
DETECTOR (GELI,PROPC) Ge(Li) diode gamma-ray spectrometer, C196200100011
calibrated proportional counter for proton monitoring. C196200100012

METHOD (GSPEC,EXTB,ACTIV) Liquid argon was bombarded with C196200100015
310-, 425-, and 578-MeV protons. Immediately after C196200100016
each irradiation, the liquid argon was transferred C196200100017
from the "irradiation" Dewar to a precooled C196200100018
"counting" Dewar and counted at varying distances up C196200100019
to 12 in. from a 3.6-cm3 Ge(Li) diode gamma-ray C196200100020
spectrometer. Pulses were stored in a Nuclear Data C196200100021
multichannel analyzer, utilizing 1024 channels C196200100022
calibrated at either 3 or 6 keV per channel. C196200100023
Successive counting periods of 20 to 8000 sec were C196200100024
taken for several hours after each irradiation so C196200100025
that decay curves were obtained for use in the data C196200100026
analysis. The counting efficiency as a function of C196200100027
gamma-ray energy deposited in the diode was obtained C196200100028
by calibration of known radionuclide sources which C196200100029
were standardized against IAEA standards. The C196200100030
"irradiation" Dewar was swabbed with alcohol and dry C196200100031
tissues which were counted to determine what, if any, C196200100032
quantity of spallation products had adhered to the C196200100033
sides of the Dewar. The empty, wiped Dewar was also C196200100034
counted to ensure that no spallation products C196200100035
remained. The collection efficiency of the swabs for C196200100036
the long-lived radioisotopes 24Na, 22Na, and 7Be was C196200100037
found to be greater than 98% based on a comparison of C196200100038
the activity of 24Na measured in the Dewar containing C196200100039
the argon and in the swabs. C196200100040
ERR-ANALYS (ERR-T) The cross section error values listed in the C196200100041
tables for the experimental data are consistent with C196200100042
the errors associated with counting statistics, C196200100043
counter calibration, proton flux, effective target C196200100044
thickness, background, and Compton production. C196200100045
(ERR-S) Since a rather large uncertainty is associated C196200100046
with the proton flux, the ratio of the cross section C196200100047
of the various radioisotopes to that of 38Cl is also C196200100048
given. Only statistical uncertainties remain in the C196200100049
ratios; hence, the ratios are much more precisely C196200100050
known. This uncertainty was calculated according to C196200100051
sigma(ratio)=(ratio)x[(sigmay/Dy)2+(sigma38/D38)2 ]1/2,C196200100052
where sigmay and sigma38 are the uncertainties, C196200100053
and Dy and D38 the disintegration rates of the various C196200100054
radioisotopes and 38Cl, respectively. C196200100055
