O157800100013 ADD-RES The singles of the gamma-ray spectra of the thorium O157800100014 fraction separated from the bombarded uranium target O157800100015 is observed. O157800100016 DETECTOR (HPGE) The detector has an energy resolution of 2.1 keVO157800100017 (FWHM) for the 1332 keV line of Co-60 and an O157800100018 efficiency of 30%. O157800100019 INC-SPECT *EN-RSL-FW*.The energy resolution. O157800100020 FACILITY (CYCLO,3CPRIMP) the Heavy Ion Research Facility in O157800100021 Lanzhou of the Institute of Modern Physics. O157800100022 METHOD (CHSEP) The chemical yield of thorium in the entire O157800100023 procedure was determined to be 70%. O157800100024 COMMENT *By authors*.The Th-236 isotope was identified by O157800100025 the characteristic gamma-rays of 642.2, 687.6 and O157800100026 229.6 keV.
