C193800100018 (IOCH) Energy loss of scattered ions was measured by C193800100019 the S800 ionization chamber C193800100020 (SCIN) Time-of-flight information was measured C193800100021 between two plastic scintillators C193800100022 (DRFTC) Two position-sensitive cathode readout drift C193800100023 chambers in the S800 focal plane provided xy C193800100024 information which, when combined with ray tracing in C193800100025 the spectrograph, allowed for an event-by-event C193800100026 determination of the projectile's scattering angle at C193800100027 the target position C193800100028 (HPGE) The segmented germanium array, consisting of C193800100029 17, 32-fold segmented, high-purity germanium C193800100030 detectors, surrounded the Coulomb excitation target C193800100031 in front of the S800 spectrograph to detect the C193800100032 de-excitation gamma rays. The high degree of C193800100033 segmentation of the gamma detectors enabled C193800100034 event-by-event Doppler reconstruction of gamma rays C193800100035 emitted in flight by the scattered projectiles with C193800100036 velocities approx. 40% of velocity of light. C193800100037 METHOD (COINC) Coincidence between focal plane detector and C193800100038 gamma detector array was required. C193800100039 Mass and charge of scattered ions were measured using C193800100040 two-dimensional plot dE x TOF, where dE was measured C193800100041 by ionization chamber and time of flight by a pair of C193800100042 plastic scintillators. Coulomb excitation was selected C193800100043 by selection of events where the projectile scattering C193800100044 angle was lower than ANG-MAX C193800100045 INC-SOURCE 58,60,62Cr beams were produced by projectile C193800100046 fragmentation of 76Ge beam with energy of 130 MeV/A on C193800100047 423 mg/cm2 9Be production target. The momentum C193800100048 acceptance of the separator was set to 0.5% for 58Cr C193800100049 and 3%for 60,62Cr C193800100050 ERR-ANALYS (DATA-ERR) No information given C193800100051 HISTORY (20120822C) Compiled by S.H.
