The different F070200200005 proton spectra associated with a particular angle were F070200200006 summed after corrections for kinematic shift. F070200200007 DETECTOR (SIBAR) A surface barrier particle detector placed at F070200200008 an angle of 120 degr. with respect to the direction of F070200200009 the incident beam was used. F070200200010 (GELI) Coincident gamma rays were detected with a 70 F070200200011 cm3 Ge(Li) detector placed at 90 degr. with respect to F070200200012 the average direction of motion of recoiling residual F070200200013 nuclei. F070200200014 SAMPLE A target of 106 mu-g/cm2 potassium iodide (enriched F070200200015 to >99% 39K) evaporated onto a thin carbon backing F070200200016 was used.
