The liquid hydrogen was C181400100018 contained in a cylindrical cell. The target cell had C181400100019 aluminum entrance and exit windows with thicknesses C181400100020 of 0.22 mm and diameters of 30 mm.The average C181400100021 mid-target energy of 74Ni was 81 MeV/nucleon. C181400100022 DETECTOR (MAGSP) The reaction residues were analyzed with the C181400100023 S800 spectrograph, whose magnetic field was set to C181400100024 transmit the scattered 74Ni ions.The particle C181400100025 identification was performed by combining B-rho, E-dE, C181400100026 and TOF measured by focal-plane detectors of the S800. C181400100027 (MWDC) Ion momentum was determined by two position C181400100028 sensitive cathode readout drift chambers. C181400100029 (TELES,IOCH,SCIN) An ionization chamber located C181400100030 downstream of the drift chambers provided the dE C181400100031 information. For the TOF, the flight time differences C181400100032 between the target position and the final focal plane C181400100033 were used, the former being extracted from the time C181400100034 measured by the plastic scintillator at the exit of theC181400100035 A1900 and B*rho of the incident beam. C181400100036 (NAICR) The gamma rays emitted from the excited C181400100037 nuclei were detected by a barrel array of NaI(Tl) C181400100038 scintillators with an inner diameter of 43 cm C181400100039 surrounding the liquid hydrogen target. The array C181400100040 consisted of 21 NaI(Tl) scintillator bars, each of C181400100041 which was 55.0 cm long and had a trapezoidal cross C181400100042 section with a height of 6.0 cm and upper and lower C181400100043 bases of 5.5 cm and 7.0 cm, respectively. The barrel C181400100044 covered a polar-angle range from 38 to 122 deg with C181400100045 respect to the beam axis. C181400100046 METHOD (EDE) E-dE method was used for particle identification C181400100047 (COINC) Coincidence was required between 74Ni ions C181400100048 detected by detectors in S800 focal plane and C181400100049 NaI(Tl) gamma ray detectors C181400100050 INC-SOURCE (KINDT) A 86Kr primary beam accelerated to 140 C181400100051 MeV/nucleon by the Coupled Cyclotron Facility was C181400100052 directed onto a 399-mg/cm2-thick 9Be fragmentation C181400100053 target at a typical intensity of 20 particle nA. The C181400100054 produced fragments were selected and separated by the C181400100055 A1900 fragment separator. C181400100056 HISTORY (20100923C) Compiled by S.H.
