  By using semi-analytical method,we investigate the transmission and
reflection coefficient and absorption and scattering cross section of spin
0,1,2 particles which are massless from a charged non rotating black holes.
Here orbiting scattering can be characterized of massless particles from
Reissner-Nordstrom black hole at a critical angular momentum. We examine the
effects upon reflection,transmission,scattering and absorption cross section
due to the black hole charge. We find that with the increase of charge the
absorption cross section decreased in spin-2 particle while in case of spin 0
particle it is reversed and in case of spin 1 the effect is negligible due to
charge.
