O161300100020 METHOD (COINC) All the cross sections presented in this paper O161300100021 are those from the analysis of the coincidence O161300100022 spectra.

O161300100035 DETECTOR (MAGSP) magnetic spectrometer (SPEG) (see Nucl.Instr. O161300100036 Meth. A276 (1989) 509-520)). O161300100037 High energy light particles such as deuterons with O161300100038 energy more or equal 2 MeV were not stopped in the MayaO161300100039 gas volume. For such escaping particles, was added O161300100040 ancillary 500-mum Si detector. O161300100041 For normalization purposes the beam was counted in a O161300100042 polycrystalline diamond detector of 1-cm**2 surface andO161300100043 100-mum thickness, after traversing the Maya target. O161300100044 (IOCH) O161300100045 (SCIN) a thick plastic scintillator. O161300100046 (PS) The angles of the incident beam particles were O161300100047 measured event-by-event using two position sensitive O161300100048 drift chambers. The combined efficiency of the two O161300100049 chambers was approximately 88% for the Be-11 beam and O161300100050 96% for the N-15 beam. O161300100051 A position-sensitive microchannel detector was used as O161300100052 a diagnostic device. O161300100053 (PSSCN) The recoiling deuterons were detected in an O161300100054 array of ten position-sensitive sheet-resistive siliconO161300100055 detectors(CHARISSA). Each detector was 5*5-cm**2 in O161300100056 area and 500-mum thick. O161300100057 ADD-RES (COMP).DWBA with random phase approximation transition O161300100058 densities. O161300100059 COMMENT *By authors*.The contribution of the deuteron breakup O161300100060 was estimated from direct kinematic measurement for O161300100061 Ni-58 at 50 A*MeV at larger angles c.m more than 8- O161300100062 degree. These data are extrapolated to lower angles andO161300100063 transformed to the reverse kinematics frame, corrected O161300100064 for the geometrical acceptance of the Maya detector andO161300100065 normalized to the experimental data(see fig.1).
