La. Khein et Av. Plyasheshnikov, ALBEDO OF PHOTONS IN HIGH-ENERGY ELECTROMAGNETIC AND HADRONIC CASCADES, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 342(2-3), 1994, pp. 451-457
The albedo of photons in electromagnetic cascades is simulated. A simp
le model of back current photons generation and propagation in electro
magnetic cascades is considered which satisfactorily describes the gen
eral features of albedo behavior. The contribution to the photonic alb
edo of electromagnetic subshowers generated by high energy gamma-quant
a from pi0 decays in the hadron initiated cascade is evalulated.
