Nuclear orientation study of the decay of172Lu

Abstract
Angular distribution of 64 gamma rays in 172Yb have been measured from the decay of 172Lu polarised at low temperatures in gadolinium and iron hosts. Multipole mixing ratios, delta , of 60 transitions have been deduced, 51 of them uniquely. From the experimental values of K conversion coefficients and E2/M1 mixing ratios the authors have determined E0/E2 mixing ratios, mod q mod , for four transitions and deduced the corresponding X(E0/E2) and mod rho (E0) mod values. Energy levels and B(E2), X(E0/E2), mod rho (E0) mod and delta (E2/M1) values have been calculated using the IBA-1 model.
