    -ray transitions of energy 2.034 0.023 MeV in the hypernucleus Li7 and 3.079 0.040 MeV in the hypernucleus Be9 are observed. In both cases, the energy of the ray in the hypernucleus ZA is very close to the energy of the first excited state of the nuclear core. The rays are interpreted as arising from core transitions in the presence of the particle. The size of the shift places limits on the strength of the N spin-dependent interaction.
