    Search for nucleon decays induced by GUT magnetic monopoles with the MACRO experiment

    The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion-number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon dec...

    Search for cosmic ray point sources with the MACRO detector at Gran Sasso

    Using a sample of 38.5 million underground muons collected by the MACRO detector we have performed an all-sky search for pointlike sourcesproducing excesses of muons above the expected background. The d.c. muo...

    Strong enhancement of transient magnetic fields in Gd over Fe for oxygen ions at high velocities

    Precision data on transient magnetic fields (TF) in ferromagnetic Gd and Fe were obtained for oxygen ions at velocities between 2 and 8v 0 (v 0=c/137) using the16O(3−) state as probe. At the high velocities the T...
