Abstract
A number of magnetic dipole γ-ray transitions have been studied using a coincidence circuit of short resolving time (2τ0 = 2 × 10−9 sec), a two lens single β-ray spectrometer, a pair of lens spectrometers placed end to end with coincidence counting of the focused radiations from a single source, and a scintillation spectrometer. Lifetimes have been measured using the delayed coincidence method and where feasible conversion coefficients and K/L ratios obtained. Comparison is made with theoretical estimates of the lifetime–energy relation for M1 γ-ray transitions.The new results are as follows:Keywords
