Abstract

A search for radiative transitions between 0.100 and 0.9 MeV from the p-shell hypernucleus B10 was undertaken. Of special interest are the M1 spin-flip transitions between members of the doublet formed by coupling an s-shell hyperon to the nuclear core. No such transitions were observed in this energy range attributable to B10. This negative result provides additional constraints on the parameters of the p-shell -nucleon effective potential. Evidence is presented of the observation of a ray which may be attributed to either the hyperfragment Li8 or Be8. A cross section for the exclusive reaction Li7(,)7o/rLi* (Ex=478 keV) of 2.20.3 mb/sr was also obtained.
