Observation of a set of nuclear shell orbitals for the Λ particle in 32ΛS and 40ΛCa

Energy excitation spectra have been obtained for hypernuclei in the s‐d shell from (K−,π−) reaction in flight on 32ΛS and 40ΛCa. The analysis is carried out in a simple particle hole model and leads to the results that the Λ behaves in the nucleus like an independant particle in a harmonic oscillator potential well with no significant spin orbit term.
