C3049001 16 SAMPLE (7-N-15,ENR=0.995) The Ti 15N target was fabricated C3049001 17 at the Forschungszentrum Karlsruhe through reactive C3049001 18 sputtering of Ti in a 99.5% enriched 15N environment. C3049001 19 The energy loss of the beam in the target at Ec.m. = C3049001 20 1323 keV was deduced from the excitation function to C3049001 21 be 11.7+-0.7 keV in the center of mass frame using C3049001 22 the full width at half maximum (FWHM) from the thick C3049001 23 target yield. The stability of the target was C3049001 24 verified by checking the yield of the Ec.m. = 1323 C3049001 25 keV resonance at various times throughout the C3049001 26 experiment. No target material loss was observed C3049001 27 during the close distance measurements. However, a C3049001 28 23% reduction in Ti 15N content was observed after C3049001 29 depositing 0.7 C of beam from the longer duration, C3049001 30 far distance, measurements at Ec.m. = 1323 keV.
