We observed RX J0852.0−4622 with the CANGAROO-II telescope from the middle of December, 2001, to the end of February, 2002, to search for sub-TeV gamma-rays. A preliminary analysis shows an apparent excess of gamma-ray-like events in alpha distribution from RX J0852.0−4622, which is to be examined in continued analyses and further observations.enConference paper00300012352009043014511265241Clay, R.
