Abstract:

The following conclusions are drawn on the basis of 228 negative and 291 positive stoppings for which Cerenkov light was recorded 1 No resolved mass measurement in the 550 region was obtained 2 If a mass 550 particle had produced Cerenkov light and stopped in the range hodoscope it is unlikely that it would have had the appearance of one of the observed events 3 If a mass 550 particle had produced Cerenkov li ht and stopped in the range hodoscope, it would have been resolved, partially resolved or not resolved depending on its range channel. No information is furnished by the group of 29 events for which no Cerenkov light was recorded. The measurement of Cerenkov light, originally intended as a safeguard against the unusual type of error, which affects only a few measurements, was not used in this manner since no resolved mass 550 measurements, were found. The likelihood of obtaining higher mass measurements than those observed is 88 if mass 550 particles occur with a relative abundance, R, of 1200 and is plotted vs R. Author
