摘要

A good agreement of the results of standardization of ↑(139)Ce by the TDCR method using RC and LPRI LS-counters was obtained. The results were confirmed by the 4πβ (LS)-λ, coincidence, 4πγ(NaI), 4πβ (PC)-γ, coincidence and X and I, spectrometer methods. The detection efficiency determination was improved by calculation of the Compton effect scintillation spectrum including the scattered photons events.A substantial modification of the TDCR method was introduced by a new parameter K3 = 132L纽?ε↑(3)↓(D) being the triple to double in third power counting efficiency ratio.#1998 Elsevier Science Ltd.
