Undertaking the study of scattering of photon by monopole and dyon it has b
een shown that photon associated with monopole and dyon has enormously high
energy. It has also been shown that two photons are necessary fdr Compton
scattering of dyon through S-matrix expansion. Study of bound state of a dy
on and an anti-dyon has also been carried out and it has been shown that th
is state is very short lived and decays in to four or six phot;ins dependin
g on the spin statistics of the dyons involved.
