Summary

A new Ge detector array dedicated to gamma-ray spectroscopy of hypernuclei with a strangeness degree of freedom has nearly been constructed. This array, aka Hyperball-J, will be installed as soon as this fall at the K1.8 beam line of J-PARC for the gamma-ray spectroscopy of light lambda hypernuclei such as 4He-lambda and 19F-lambda in its inaugural run. Hyperball-J has some features that are unconventional in Ge arrays for gamma-ray spectroscopy of non-strange nuclei. In this presentation, physics that can be accessed via the hypernuclar spectroscopy will be discussed together with description of Hyperball-J. Also a possible use of high resolution and high efficiency scintillators for detecting lambda inter-shell transitions of lambda hypernuclei in the sd-shell will be mentioned.
