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
