Abstract
An analysis has been made of gamma rays from the Large Magellanic Clou d (LMC) using data from the Compton Gamma Ray Observatory. After corre cting for foreground gamma rays from cosmic ray (CR) interactions in o ur own Galaxy it is found that the gamma ray intensity maps show a dis placement of peak position away from the peak of the atomic gas contou rs and towards the peak of the starlight contours. An explanation is a dvanced in terms of there being an increasing contribution from invers e Compton interactions, this contribution being bigger the higher the energy. Our earlier contention that the average cosmic ray intensity w ithin the LMC is only about 15% of that in the Galaxy is confirmed.
