Abstract
It is shown that the mean deviation (experimental versus calculated) o f the energy level fit in the crystal field analysis of U4+ in Cs2UBr6 and Cs2ZrBr6 falls from 208 to 43 cm(-1) when configuration interacti on between the ground configuration 5f(2) and 5f(1)7p(1) is taken into account. A drastic decrease of the gap between the two configurations is required to give an optimum data fit.
