Supersymmetric and Strangeness-Analog States inp-ShellΛHypernuclei

Shell model analysis of ?-hypernuclear spectra for massA=12 andA=16

“…In such a description, the amplitude is proportional to the momentum distribution of nucleons before their conversion into hyperons. Dalitz and Gal [20] have calculated the quasi-free spectrum for X-hypernuclei. Recently Kishimoto [21] has used the same mechanism to estimate the quasi-free background of X-hypernuclear spectra.…”

Strangeness-exchange and strange nuclei

“…In the SU(3) limit for the spinorbit strength, Os = 0, only one state is expected to be observed. Note, however, that even for zero strength fa~ the A spin-orbit, corresponding in 16 o to os= 4 MeV, the relative formation rate of the lower state is quite low, ranging bet~een 0.17 and 0.09 as£' varies from 0 to 0.5. If ill: is fixed at the "observed" value of"' 5.5 HeV, a range of os between 2 to -2 MeV is allowed as £' is varied from 0 to 0.5; however, the relative formation rate for the lower state is 20 smaller than 10%, considerably less than the Heidelberg group •would like to extract from the raw data.…”
