The RbCl sample with 3280100100016 thickness of 1.0 mm and diameter of 20 mm was made by 3280100100017 pressing RbCl powder with purity of 99.50%. 3280100100018 DETECTOR (GE) A high resolution Ge detector (ORTEC GEM60P) 3280100100019 with high efficiency (relative efficiency of 60%). 3280100100020 The efficiency calibration of Ge has been done 3280100100021 carefully with a set of standard gamma-ray sources 3280100100022 including 152Eu, 226Ra, 133Ba, and 60Co procured by 3280100100023 England Aeatechnology. The detector efficiency for 3280100100024 1332 keV is 0.00482. 3280100100025 METHOD (ACTIV) The 85Rb samples were irradiated about 107 h 3280100100026 on the surface of a two-ring orientation assembly, 3280100100027 placed at the angles of 0, 29, 48, 64, 79, 94, 110, 3280100100028 129, and 161 deg with respect to the deuteron beam 3280100100029 direction and TiT target center. The irradiation 3280100100030 history can be divided into any number of separate 3280100100031 parts, each with a relative neutron flux given by the 3280100100032 counts. The total neutron flux, as measured by the 3280100100033 93Nb(n,2n)92mNb monitor reaction, is apportioned 3280100100034 into each irradiation step. 3280100100035 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3280100100036 DECAY-MON (41-NB-92-M,10.15D,DG,934.44,0.9915) 3280100100037 MONIT-REF (,S.A.Badikov+,C,93VAIL,,,1993) 3280100100038 The used standard cross-section data were conducted 3280100100039 by the interpolation method. 3280100100040 CORRECTION Corrections were made for self-absorption in the 3280100100041 sample. 3280100100042 ERR-ANALYS (ERR-T) The main uncertainty sources were due to the 3280100100043 gamma-ray detector efficiency, counting statistics, 3280100100044 and standard cross-section. 3280100100045 (ERR-S,1.0,2.0) The statistical uncertainty 3280100100046 (ERR-1) The gamma-ray detecting efficiency 3280100100047 (ERR-2) The self-absorption 3280100100048 (MONIT-ERR,0.7,1.5) The standard cross-section 3280100100049 STATUS (TABLE) Table 3 of Chinese Phys.
