C265300100009 SAMPLE The targets, consisting of approximately 200 C265300100010 microg/cm2 of gold vaporized onto 0.1-mil aluminum C265300100011 backing foil, were oriented at 45 deg to the beam, C265300100012 with the gold facing toward or away from the beam C265300100013 when fragments were observed at backward or forward C265300100014 angles, respectively. C265300100015 DETECTOR (SCIN) C265300100016 METHOD Angular-distribution experiments were performed in C265300100017 the vacuum tank. The energy of the carbon ions was C265300100018 varied by placing aluminum degrading foils in the C265300100019 beam path ahead of the vacuum tank. A simpler C265300100020 arrangement, in which a gas scintillation counter was C265300100021 fixed at 90 deg to the beam, was used for experiments C265300100022 in which it was necessary to observe fragments only C265300100023 at 90 deg to the beam.
