Dm. Timus, SHORT CONTRIBUTION TO LOW-ORDER APPROXIMATION STUDY OF ANISOTROPICALLY EMITTING RECTANGULAR SOURCES, Journal of Nuclear Science and Technology, 32(9), 1995, pp. 928-935
Contribution of a further term in low approximation of anisotropically
emitting rectangular source, in nondispersive media is presented. Ana
lytical, desk computable expression for the fourth component of the ra
diation field as well as its relation with isotropic, omnidirectionall
y emitted component are given. Perfect agreement with basic Hubbell's
results is underlined.
