Energy and3222400100040 efficiency calibration of spectrometer was done with 3222400100041 133Ba, 152Eu, 57Co, 60Co, 137Cs standard sources. 3222400100042 (SPEC,GELI) Spectrometer with Ge(Li) detector 3222400100043 DGDK-32B was placed at the horizontal channel and used 3222400100044 to determine the incident neutron flux using reaction 3222400100045 10B(n,alpha+gamma). 3222400100046 (HE3SP)Exposing the tantalic targets, simultaneously 3222400100047 the monitoring of the neutron flux has been done by the3222400100048 neutron spectrometer with 3He-counter. 3222400100049 METHOD (ACTIV,GSPEC) 3222400100050 SAMPLE For measurements at filtered beam: 3222400100051 Thicknesses of Ta and In samples are 100 micro-m and 3222400100052 650 micro-m correspondingly. The diameters of tantalum 3222400100053 foil sample and In foil sample were the same and equal 3222400100054 to 28.2 mm. The 115In(n,g)116mIn reaction was used for 3222400100055 monitoring an absolute value of neutron flux. 3222400100056 For measurements at 2.85 and 14.34 MeV: 3222400100057 Thicknesses of Ta samples were 400 micro-m, diameters 3222400100058 equal to 13, 14, and 18.5 mm. 3222400100059 MONITOR (49-IN-115(N,G)49-IN-116-M,,SIG) 3222400100060 (40-ZR-90(N,2N)40-ZR-89,,SIG) 3222400100061 (41-NB-93(N,2N)41-NB-92-M,,SIG) 3222400100062 CORRECTION Due to short half-time and varying activity during the 3222400100063 time of measurement the differential method has been 3222400100064 utilized to make the correction for "dead" time effect.3222400100065 True coincidence and self absorption effect were taken 3222400100066 into account. 3222400100067 DECAY-DATA Decay data for all considered reactions and monitors 3222400100068 were taken from Richard B.
