Although numerous results for the L/K-capture ratio are reported, there are only a very few cases in which the precision of the results are such that they may be compared critically with theory. This situation results from the difficulty of making corrections for the escape of K x rays from the counter. For low and medium weight elements a further difficulty exists in that the L x rays, which are of low energy, are absorbed before they reach the sensitive volume of the counter. To overcome these problems, a multiwire counter with internal anticoincidence was constracted in which the source could be introduced directly into the counter as a gas. In this system the correction for escape is reduced to a few percent. The availability of the ferrocene type compounds, which have an appreciable vapor pressure, made the possibility of L/K-capture ratio measurements on Fe/sup 5//sup 5/ and Co/sup 5//sup 8/ especially attractive. For Fe/sup 5/>s5< s the ratio, P/sub L/P/sub K/ = 0.106 plus or minus 0.005, and for Co/sup 5//sup 8/ P/sub L//P/sub k/ = 0.108 plus or minus 0.004. When compared with theory (Brysk & Rose), the values agree within 10 and 20%, respectively, the experimental values being slightly larger than the theoretical predictions. The discrepancy is discussed in the light of the correction of Odiot and Daudel, but it remains largely unexplained. (auth)
