  4. Recently, there was another double hypernuclear event reported byJ. Lemonne, J. Sacton, G. Schorochoff, D. O’Sullivan, T. P. Shah, A. Thompson,Sr. M. Heeran, A. Montwill, R. O. Stanley, M. A. Shaukat, W. T. Toner, P. Allen, D. H. Davis, E. R. Fletcher, J. E. Allen, V. A. Bull, A. P. Conway, M. M. Kasim, P. V. March, K. Pniewska, T. Pniewski, M. F. Votruba, M. Suk, Z. Vintz, A. Filipkowski, J. Herynek, J. Piekarz andJ. Zakrzewski:Nuovo Cimento,41, 235 (1966). This event is, however, not useful for our purpose, since its identity could not be established.

  5. In a number of detailed calculations (ref. (5–8)), the identification as10BeΛΛ has always been assumed. This is perhaps not too serious, since, as pointed out by Dalitz (R. H. Dalitz:Phys. Lett.,5, 53 (1963)), the analysis of this event as11BeΛΛ would likely lead to a similar estimate for the Λ-Λ strength. Also, the analysis ofDanysz et al. showed that those interpretations in terms of litbium double hyperfragments appeared to be less likely.

  15. The small difference between the α-A potential of this calculation (potentialA) and that of ref. (7) has been taken into consideration.

  16. Danysz et. al. gaveB ΛΛ=(17.5±0.5) MeV, which was based onB Λ for9BeΛ equal to 6.5 MeV. We have revised the value ofB ΛΛ, since the most recent experimental value ofB Λ for3BeΛ is (6.24±0.25) MeV (10).

  17. Similar conclusions should hold, if this double hypernucleus were11BeΛΛ.
