  The present status of hypernuclear gamma-ray spectroscopy with Hyperball is
summarized. We observed two gamma transitions of 16-Lambda-O(1- -> 1-,0-) and
obtained the strength of the Lambda-N tensor force. In 10B(K-,pi- gamma) data,
we did not observe the spin-flip M1 transition of 10-Lambda-B(2- -> 1-), but
gamma rays from hyperfragments such as 7-Lambda-Li(7/2+ -> 5/2+) and
9-Lambda-Be(3/2+ ->1/2+) were observed. In 11B(pi+,K+ gamma) data, we observed
six gamma transitions of 11_Lambda-B. We also attempted an inclusive gamma-ray
measurement with stopped K- beam.
