F151100100021 FACILITY (CYCLO,4ZZZDUB) U-400M cyclotron (primary 11B beam) F151100100022 INC-SOURCE Primary 11B beam intensity was ~ 1p mu-A, 33.4 MeV. F151100100023 METHOD (EDE,TOF) F151100100024 (COINC) The 3He recoils were detected in coincidence F151100100025 with 3H. Triple coincidence events 3H-3He-n were also F151100100026 recorded. F151100100027 DETECTOR (TELES,SISD) 3He telescope assembly was installed at F151100100028 a distance of 179 mm from the target. It consisted of F151100100029 four identical dE-E-E telescopes made of the silicon F151100100030 strip detectors (SSD). The 20-mu-thick SSD with a F151100100031 sensitive area of 50x50 mm2 was divided into 16 strips,F151100100032 the second and the third layers were created by the twoF151100100033 identical 1-mm-thick SSDs (60x60 mm2 with 16 strips). F151100100034 The angular range covered by these 3 telescopes F151100100035 for the 3He recoil nuclei was extended up to the F151100100036 range from ~6 to ~24 degrees in the laboratory system. F151100100037 Tritons originating from 7H were detected using the F151100100038 setup where the central telescope was placed at a F151100100039 distance of 323 mm from the target. It consisted of oneF151100100040 1.5-mm-thick double-sided SSD (64x64 mm2, with 32 F151100100041 strips on each side) followed by a square array of 16 F151100100042 CsI(Tl) crystals. F151100100043 (SCIN) Neutron spectrometer, made of 48 organic F151100100044 scintillator modules was used. F151100100045 SAMPLE Primary 11B beam bombarded the 1-mm thick beryllium F151100100046 production target. The secondary 8He beam with F151100100047 intensity ~10**5 pps, was focused on the deuterium F151100100048 gas target. The 4-mm-thick target cell, equipped with F151100100049 the 6-mu-thick and 25-mm diameter stainless-steel F151100100050 entrance and exit windows, was cooled down to 27 K F151100100051 and filled with the deuterium gas up to a pressure at F151100100052 which the target thickness was ~3.7x10**2 cm(-2). F151100100053 PART-DET (HE3,T) F151100100054 EN-SEC (E,1-H-7) Decay energy above the 3H+4n threshold is F151100100055 given. F151100100056 ADD-RES H-2(Be-10,He-3)Li-9 g.s. was studied at 42 A MeV 10Be F151100100057 secondary beam. The cross-section values of ~7-10 mb/srF151100100058 at forward angles in the center-of-mass system were F151100100059 deduced for the 9Li ground state. F151100100060 (STRUC) With obtained 7H spectra the authors assign theF151100100061 ground state at 2.2(3) MeV, the first excited state at F151100100062 5.5(3) MeV, and the higher-energy resonances at 7.5(3) F151100100063 and 11.0(5) MeV.
