INC-SOURCE The terminally pulsed 4He+ e beam (currents <= 5 mA).  C2910001   11 
           The He+ pulses had a time resolution (FWHM) of less    C2910001   12 
           than 2 nsec.                                           C2910001   13

DETECTOR   (NAICR) A relatively large (23- by 30-cm) NaI(Tl)      C2910001   15 
           scintillator viewed by six matched bialkali            C2910001   16 
           photomultiplier tubes was used.                        C2910001   17 
SAMPLE     Targets were fabricated by "cracking" enriched         C2910001   18

           0.025-cm tantalum backings. Thicknesses determined by  C2910001   20 
           weighing (with a microbalance) the backings before     C2910001   21 
           and after deposition ranged between 98+/-2 and         C2910001   22
