E185400100013 INC-SOURCE Beam intensity is about 1.4e11 PPS. (Beam intensity E185400100014 was continuously monitored by a SEC (secondary E185400100015 emission chamber), which was calibrated by the E185400100016 activation method using the 27Al(p,3pn)24Na reaction.) E185400100017 SAMPLE - Chemical-form of target is element. E185400100018 - Physical-form of target is solid. Thin metal foil E185400100019 target. Each target consists of three stacked foils E185400100020 of the same thickness. A middle foil was used for E185400100021 counting and chemical assays, while the outer foils E185400100022 served to compensate for recoil loss. Each target E185400100023 was bundled together and placed in order of target E185400100024 atomic weight. E185400100025 METHOD (ACTIV)Irradiation time was 37 min. E185400100026 (EXTB)Average intensity of proton beam was 1.4e+11 E185400100027 proton/sec. E185400100028 (CHSEP)Irradiated targets were stored in a E185400100029 refrigerator (about 6 deg), and the tritium E185400100030 analysis was carried out about three months E185400100031 after the bombardment. The irradiated foil was E185400100032 dissolved completely in acid. See Fig.1 of E185400100033 reference for the dissolution apparatus used in E185400100034 this experiment. E185400100035 FACILITY (SYNCH,2JPNLEP)External primary beam line of the 12 E185400100036 GeV proton synchrotron E185400100037 DETECTOR (GELI)To measure 24Na radioactivity in the Al foil E185400100038 (SCIN)To measure radioactivity of tritium. Counting E185400100039 efficiency was determined by an auto-external E185400100040 standard method using standard tritium sources, E185400100041 to be about 22%. E185400100042 CORRECTION Correction for recoil loss was made and about 10% E185400100043 error is included because of recoil correction for E185400100044 thin target.
