OSTI ID:4188916
The mass of the LAMBDA /sup 0/-hyperon was determined in nuclear emulsion from the range and the relative orientation of the decay particles of twenty-five LAMBDA /sup 0/ decays. The previous emulsion determinations of Friedlander, Q/ LAMBDA = 36.9 plus or minus 0.21 Mev, and Barkas, Q LAMBDA = 37-45 plus or minus 0.16 Mev, were in disagreement. and the average of their values led to a negative binding energy for the LAMBDA H/sup 3/ hyperfragment. The new determination resulted in a LAMBDA /sup 0/ mass of 1115.55 plus or minus 0.15 Mev, which corresponded to a Q-value of 37.71 plus or minus 0.14 Mev. This new Q-value averaged with that of Barkas yielded a binding energy for LAMBDA H/sup 3/ of +0.12 plus or minus 0.26 Mev. (auth)
