  Deep underground in Kolar Gold Fields, in southern India, an experiment to
detect proton decay had been carried out since the end of 1980. Analysis of
data yielded the following results; (l) the life time of proton is about 1 x
1031 years, (2) it decays into wide spectrum of decay modes, p -> e+ + pai0, p
->anti-nutrino + K+ and so on, and (3) the life time and the distribution of
decay modes are close to the predictions of SU(5) SUSY GUT. Four events
representing possibly neutron oscillation are also seen.
