Single-particle states in Ca have been investigated through the Ca(d, p) 'Ca reaction with polarized deuterons of Eg --56 MeV. Angular distributions of differential cross sections and vector analyzing powers were measured for 91 transitions up to 9.7-MeV excitation energy by using a magnetic spectrograph. Analyses of these data were performed to determine j and t S of singleparticle levels with zero-range distorted-wave Born approximation calculations using the adiabatic approximation. The occupation probabilities and the single-particle energies in Ca were extracted for the valence (2p -1f) and (2s -1d) shells with including previous (p, d) data. The results on these quantities show good agreement with theoretical expectations.PACS number(s): 21.10. Jx, 21.60.Cs, 25.45.Hi, 27.40.+z

The production of L hypernuclei was studied in proton reactions with Bi nuclei and the lifetime of the produced heavy hypernuclei was measured by the observation of delayed fission using the recoil shadow method. The measurements were performed at 1.9 GeV proton energy whereas the background was determined at 1.0 GeV. From the distribution of the w Ž. Ž .x fission fragments in the shadow region the lifetime t s 161 " 7 statist. " 14 system. ps was obtained and from a comparison of counting rates of prompt and delayed fission fragments the production cross section of hot L hypernuclei was Ž. determined to be 350 " 140 mb.
