“…Figure 2 gives the distribution in cos0"A for all events of this type; the shaded region corresponds to the AHe hyper fragments. The marked forward peaking of the distribution is in agreement with results of other workers (Levi-Setti et al 1958).…”

“…In these calculations the neutron energy mainly results from the momentum unbalance produced when the X H of decay ( 1) is replaced by a deuteron. The calculated values of B A are not in disagreement with the value B A = 4-8 MeV (for aLI) in the curves of B A against A published by Levi- Setti et al (1958).…”

“…The work of various groups (Deka 1957;Fry, Schneps & Swami 1955,1957Levi-Setti, Slater & Telegdi 1958) has established the existence of a series of such hyperfragments. The binding energies of the A0 for light hypernuclei (Z ^ 5) have been measured.…”

A systematic study of 260 000 stars produced by 4.3 GeV/ c negative π -mesons and of 1000 K - interaction stars, both in Ilford G 5 nuclear emulsion, yielded 46 hypernuclei decaying by the mesonic mode. The identification of these events is described and the binding energy of the Λ 0 hyperon in the nucleus is calculated in each case with the help of a program written for the Ferranti Mercury computer. The binding energies of the uniquely identified hypernuclei are found to be as follows: 4 cases of Λ H ; B Λ = 0.67 ± 0.38 MeV, 9 cases of 4 Λ H ; B Λ = 1.94 ± 0.28 MeV, 14 cases of 5 Λ H ; B Λ = 3.21 ± 0.14 MeV, 1 case of 9 Λ Li ; B Λ = 3.51 ± 3.49 MeV. All other events admit alternative interpretations, and the binding energies are tabulated for the various possibilities. Other experimental results are also discussed. The quoted errors in the binding energies are random errors; contributions from systematic sources are discussed and they amount to about 0.3 MeV.

“…The first hypernucleus was discovered by Marion Danysz and Jerzy Pniewski in 1952 in a balloon-flown emulsion plate [1]. Many other hypernuclei were observed during the following few years in emulsion experiments [2,3]. The hypertriton is the lightest hypernucleus, and is composed of a proton, a neutron, and a Λ hyperon.…”

Recalibration of the binding energy of hypernuclei measured in emulsion experiments and its implications *

The Λ separation energy for Λ-hypernuclei, denoted BΛ, measured in 1967Λ-hypernuclei, denoted BΛ, measured in , 1968Λ-hypernuclei, denoted BΛ, measured in , and 1973 are recalibrated using the current best mass estimates for particles and nuclei. The recalibrated BΛ are systematically larger (except in the case of 6 Λ He) than the original published values by about 100 keV. The effect of this level of recalibration is very important for light hypernuclei, especially for the hypertriton. The early BΛ values measured in 1967, 1968, and 1973 are widely used in theoretical research, and the new results provide better constraints on the conclusions from such studies.
