M028100100013 FACILITY (BETAT,4RUSMOS) M028100100014 INC-SOURCE (BRST) M028100100015 INC-SPECT Gamma-beam near the target has right-angled form M028100100016 1.2 * 10.0 cm**2 (last dimension is vertical). M028100100017 METHOD (REC,PSD) Zero-crossing method. M028100100018 DETECTOR (SCIN) NE-213 type liquid scintillator of 20 mm thick M028100100019 in glass container of 30 mm diameter with 3.5 cm lead M028100100020 shield in front of the detector. AVP-56 multiplier, M028100100021 4096-channel amplitude analyzer working in M028100100022 two-dimensional regime. M028100100023 PART-DET (P) M028100100024 ANALYSIS Statistical theory of nuclear reactions was used. M028100100025 CORRECTION Corrected for background and for the interaction of M028100100026 neutrons with the lead shield. M028100100027 ERR-ANALYS (ERR-S) Statistical errors are presented. M028100100028 ADD-RES (COMP) a statistical theory of nuclear reactions was M028100100029 used. Nuclear temperatures and level density M028100100030 parameters were obtained. M028100100031 COMMENT Comparison of the obtained experimental results with M028100100032 the predictions of the statistical theory of nuclear M028100100033 reactions shows that the theory does not describe the M028100100034 decay of nuclear collective states of the kind of M028100100035 the giant dipole resonance.
