C306400100011 INC-SPECT The secondary beam of interest, 25Al, had an average C306400100012 beam intensity of 7.5*10**3 particles per second, 25% C306400100013 of the total number of particles reaching the C306400100014 secondary target. The 25Al beam particles were also C306400100015 identified and selected during the event analysis C306400100016 through their characteristic time correlation with C306400100017 the accelerator RF reference. The optimal beam C306400100018 intensity was obtained at a magnetic rigidity of C306400100019 0.5597 Tm, corresponding to 102 MeV of 25Al in the C306400100020 13+ charge state. C306400100021 DETECTOR (SI) For detection of the decay protons, two annular C306400100022 Micron Semiconductor S2-type detectors with 64 microm C306400100023 and 1000 microm thicknesses were positioned at 69 mm C306400100024 and 82 mm downstream of the target, subtending angles C306400100025 between 8 and 22 degree from the beam axis.

The target thickness was then C306400100029 determined by weighing the resulting foil before it wasC306400100030 cut and mounted on targets frames.

C306400300009 The reaction mechanism was investigated using a CRC C306400300010 calculation using the program FRESCO. Applying the C306400300011 mirror-nucleus spectroscopic factors directly would C306400300012 predict a slightly higher cross section than C306400300013 measured. We therefore scaled the spectroscopic C306400300014 factors of Hamill et al. down to reproduce the C306400300015 observed cross section, while retaining the l=0/l=2 C306400300016 ratio. In order to extract the proton-resonance width C306400300017 from the l=0 spectroscopic factor, the R-matrix C306400300018 expression was employed GammaP = C**2*Sl=0*GammaS.P., C306400300019 where C**2*Sl=0 is a spectroscopic factor and C306400300020 GammaS.P. is a single particle width.
