F139300100012 METHOD (INTB) The target was irradiated for 120 sec. F139300100013 (ASPEC) F139300100014 DETECTOR (PLATE,SCIN,CSICR) NIKFI-T-1 nuclear emulsion and a F139300100015 scintillation alpha spectrometer with a thin (0.2- F139300100016 0.3 mm) CsI(Tl) crystal were used. The crystal was F139300100017 introduced into the vacuum section of the probe and F139300100018 the light was brought to an FEU-11-B photomultiplier F139300100019 through a light pipe 20 cm long.
