title: Search for magnetic monopoles in the lunar sample.
abstract: An electromagnetic search for magnetic monopoles of the minimum size predicted by Dirac, or of any larger magnitude, has been performed on 8.37 kilograms of lunar surface material. No monopole was found. This experimnent sets new limists on the production cross section for monopoles and on their occurrence in cosmic radiation.
