Abstract

Excitation energy spectra of [Formula Presented] and [Formula Presented] have been measured via the [Formula Presented] reaction by using the SKS spectrometer at the K6 beam line in the KEK 12-GeV Proton Synchrotron. In the [Formula Presented] spectrum, obtained with an energy resolution of 1.65 MeV (FWHM) and in the highest statistics so far, we have succeeded in clearly observing a characteristic fine structure in heavy Λ hypernuclear systems and precisely obtaining a series of Λ single-particle energies in the very wide excitation energy range of more than 20 MeV, for the first time. Also in the [Formula Presented] spectrum, a similar structure to that of [Formula Presented] was observed. In the [Formula Presented] spectrum, new core-excited states were clearly resolved thanks to the best energy resolution of 1.45 MeV so far achieved by using the SKS spectrometer.
