Abstracts
Additional mass values are reported for a large number of K-mesons found in two emulsion stacks exposed to 114 MeV and 170 MeV focused K-mesons from the Bevatron. For 459 KL-mesons and 55 -mesons in stack 1 the mean values are, 971 ± 1.3 and 978 ± 4 electron masses respectively, and for 177 KL-mesons and 16 -mesons in stack 2, the values are 962 ± 1.9 and 965.4 ± 3.8 me. (Science Abstracts, 1956, 1622. D. J. Prowse).
