Seven targets with two 1468000100013 different enrichments were used. Targets with lower 1468000100014 enrichment (86.8% for 146Nd) were used mainly for 1468000100015 development of chemical separation procedure 1468000100016 (60-ND-142,ENR=0.0043) 1468000100017 (60-ND-144,ENR=0.0070) 1468000100018 (60-ND-145,ENR=0.0069) 1468000100019 (60-ND-146,ENR=0.9746) 1468000100020 (60-ND-148,ENR=0.0032) 1468000100021 (60-ND-150,ENR=0.0013) 1468000100022 DETECTOR (HPGE) Gamma rays were detected using two HPGe 1468000100023 detectors with active volume 10 and 100 cm3 with 1468000100024 resolution 1 keV at 123 keV 1.8 and 1.9 KeV at 1332 1468000100025 keV, respectively. 1468000100026 METHOD (ACTIV,CHSEP) Cross sections were determined by 1468000100027 analysing product yields and their decay variation. 1468000100028 INC-SOURCE (REAC) Irradiations were performed in center of reactor1468000100029 core with thermal neutron flux up to 2.1E+15 n/cm2/s, 1468000100030 with thermal to epithermal flux ratio of 30+-1.5 and 1468000100031 fast (En > 1 MeV) to thermal ratio approx. 0.25. 1468000100032 ERR-ANALYS (DATA-ERR) Origin of uncertainties not described 1468000100033 HISTORY (20210213C) Compiled by S.H. 1468000100034 (20240329A) OS.
