Dm. Timus, A SHORT CONTRIBUTION TO THE HUBBELL EXPRESSION FOR THE RADIATION-FIELD FROM A CLASS OF DISK-SHAPED SOURCES, Journal of radioanalytical and nuclear chemistry, 199(1), 1995, pp. 57-63
A computationally tractable expression is presented for the flux densi
ty distribution produced in nondispersive media by disk-shaped sources
, whose local emissivity is omnidirectional and governed by a radial d
ependence of even terms power series type.
