Proton D503100100009 current on target 10-15 microA. D503100100010 SAMPLE The isotopic target of 26Mg is produced by hammering ofD503100100011 the 26Mg ions in tantalum backing directly in D503100100012 electromagnetic separator.The target thickness is D503100100013 about 7 keV for protons at Ep=2.0 MeV. D503100100014 METHOD (GSPEC) D503100100015 DETECTOR (GELI) One germanium- lithium detector is used with D503100100016 an active volume of 63 cm**3 and a resolution of 3.0 D503100100017 keV at Eg=1.33 MeV. The gamma-rays were detected at D503100100018 angles of 0, 30, 45, 60 and 90 degrees in the D503100100019 laboratory system. The detector was calibrated D503100100020 using gamma-rays from reaction 27Al(p,gamma)28Si at D503100100021 proton energy 991.86(3)keV. D503100100022 (NAICR) NaI detector was used for excitation D503100100023 function measurements and as monitor of gamma D503100100024 radiation. The dimensions of the crystal was D503100100025 diameter15 x 10 cm. The gamma-rays were detected at D503100100026 angle of 55 degrees concerning proton beam direction D503100100027 with step delta Ep=1.8 keV.
