F1511 1 21 FACILITY (CYCLO,4ZZZDUB) U-400M cyclotron (primary 11B beam) F1511 1 22 INC-SOURCE Primary 11B beam intensity was ~ 1p mu-A, 33.4 MeV. F1511 1 23 METHOD (EDE,TOF) F1511 1 24 (COINC) The 3He recoils were detected in coincidence F1511 1 25 with 3H. Triple coincidence events 3H-3He-n were also F1511 1 26 recorded. F1511 1 27 DETECTOR (TELES,SISD) 3He telescope assembly was installed at F1511 1 28 a distance of 179 mm from the target. It consisted of F1511 1 29 four identical dE-E-E telescopes made of the silicon F1511 1 30 strip detectors (SSD). The 20-mu-thick SSD with a F1511 1 31 sensitive area of 50x50 mm2 was divided into 16 strips,F1511 1 32 the second and the third layers were created by the twoF1511 1 33 identical 1-mm-thick SSDs (60x60 mm2 with 16 strips). F1511 1 34 The angular range covered by these 3 telescopes F1511 1 35 for the 3He recoil nuclei was extended up to the F1511 1 36 range from ~6 to ~24 degrees in the laboratory system. F1511 1 37 Tritons originating from 7H were detected using the F1511 1 38 setup where the central telescope was placed at a F1511 1 39 distance of 323 mm from the target. It consisted of oneF1511 1 40 1.5-mm-thick double-sided SSD (64x64 mm2, with 32 F1511 1 41 strips on each side) followed by a square array of 16 F1511 1 42 CsI(Tl) crystals. F1511 1 43 (SCIN) Neutron spectrometer, made of 48 organic F1511 1 44 scintillator modules was used. F1511 1 45 SAMPLE Primary 11B beam bombarded the 1-mm thick beryllium F1511 1 46 production target. The secondary 8He beam with F1511 1 47 intensity ~10**5 pps, was focused on the deuterium F1511 1 48 gas target. The 4-mm-thick target cell, equipped with F1511 1 49 the 6-mu-thick and 25-mm diameter stainless-steel F1511 1 50 entrance and exit windows, was cooled down to 27 K F1511 1 51 and filled with the deuterium gas up to a pressure at F1511 1 52 which the target thickness was ~3.7x10**2 cm(-2). F1511 1 53 PART-DET (HE3,T) F1511 1 54 EN-SEC (E,1-H-7) Decay energy above the 3H+4n threshold is F1511 1 55 given. F1511 1 56 ADD-RES H-2(Be-10,He-3)Li-9 g.s. was studied at 42 A MeV 10Be F1511 1 57 secondary beam. The cross-section values of ~7-10 mb/srF1511 1 58 at forward angles in the center-of-mass system were F1511 1 59 deduced for the 9Li ground state. F1511 1 60 (STRUC) With obtained 7H spectra the authors assign theF1511 1 61 ground state at 2.2(3) MeV, the first excited state at F1511 1 62 5.5(3) MeV, and the higher-energy resonances at 7.5(3) F1511 1 63 and 11.0(5) MeV.
