O142500100030 (SPEC) To clearly identify the protons from the 7-Be+d O142500100031 reaction from those arising from reactions on the C O142500100032 content of the target, a stack of two 'Leda' silicon O142500100033 strip detector arrays were employed covering a O142500100034 laboratory angular range of 7.6-17.4 angular degrees. O142500100035 FACILITY (CYCLO,2BLGLVN) O142500100036 METHOD (SITA) See sample. O142500100037 (EXTB) The measurements were performed using a post- O142500100038 accelerated 7-Be+ radioactive beam at a nominal energy O142500100039 of 5.8 MeV provided by the Cyclone-110 cyclotron. O142500100040 To suppress the contamination from the 7-Li isobaric O142500100041 beam, the 7-Be beam was completely stripped to 7-Be-4+ O142500100042 by transmission through a thin 12-C foil, prior to O142500100043 analysis by a dipole magnet. O142500100044 (EDEG) O142500100045 MONITOR (6-C-12(4-BE-7,EL)6-C-12,,DA) The absolute O142500100046 normalization was obtained using events arising from O142500100047 the elastic scattering of the 7-Be on the C content of O142500100048 the target and assuming that the 7-Be+12-C elastic O142500100049 scattering follows the rutherford law. This assumption O142500100050 is realistic at energies below the coulomb barrier, as O142500100051 is the case here.
