We derive the probability and attenuation coefficients for pair creation
in first order of polarized electrons and positrons.
The positron and
electron can occupy arbitrary Landau levels and the attenuation coefficient
is evaluated for any direction and polarization of the photon.
When we take 
and sum over polarization of the spins
of the 
pair, we obtain results which differ from the expressions
for the attenuation coefficient obtained by Daugherty & Harding ([CITE]),
by the factor 
,
in agreement with Frangodimitraki-Georgiadou ([CITE]).
