Previous experiment of the group. O114100100013 SAMPLE Uranium targets were used. O114100100014 DETECTOR (D4PI,LONGC) 4-Pi neutron long detector. O114100100015 (SCIN) A thin plastic scintillator. O114100100016 (HPGE) 23% HPGE -detector. The detector was placed O114100100017 inside the neutron counter. O114100100018 FACILITY (CYCLO,2SF JYV) O114100100019 (OLMS,2SF JYV) The newly upgraded ion guide separator O114100100020 IGISOL was used to produce and separate isobarically O114100100021 pure beams of primary fission products with delay time O114100100022 of the order of milliseconds only. O114100100023 METHOD (OLMS,ACTIV) O114100100024 ANALYSIS (DECAY) O114100100025 ERR-ANALYS (DATA-ERR) No information about source of uncertainty O114100100026 ADD-RES (COMP) Quasiparticle random phase approximation. O114100100027 Decays of Y-104 with a half-life of 180+-60-msec and O114100100028 of Tc-114 with a half-life of 150+-30-msec are reportedO114100100029 for the first time. Beta-delayed neutron emission O114100100030 probabilities of Tc-112,113,114 are determined. O114100100031 HISTORY (20040312C) O114100100032 (20040415U) Last checking has been done.
