In several papers from 1959 through 1963 one finds the reference:J. Kuehner, A. W. Merrison andS. Tornabene:Proc. Phys. Soc., to be published. The value given in Samios' paper apparently contains a typographical error,i.e. it is quoted as 4.55 MeV. We checked againstHaddock et al., ref. (6)A. Abashian, K. M. Crowe, J. B. Czirr andR. P. Haddock:Phys. Rev. Lett.,3, 478 (1959). andHillman et al., ref. (7)P. Hillman, W. C. Middelkoop, T. Yamagata andE. Zavattini:Nuovo Cimento,14, 887 (1959). They both give 8.8m e forMerrison et al. which works out to 4.50 MeV. Note Samios' reference toCrowe et al. is same as ref. (6)A. Abashian, K. M. Crowe, J. B. Czirr andR. P. Haddock:Phys. Rev. Lett.,3, 478 (1959).
