A TIME CORRELATION TECHNIQUE FOR INVESTIGATING TWO CONNECTED NUCLEAR TRANSFORMATIONS. Final Report, October 1960-June 1962
Research on a time correlation method for measuring daughter half lives in the range 10/sup -4/-1 sec is reported. Expressions were derived for the average value and variance of the prompt correlation function for a long-lived parent and a delayed daughter with mean life No measurable /sup -1/ and with uncorrelated background present. The previous complicated expression derived for the variance for a delayed cascade was reduced to a tractable expression, and the analysis was extended to include background influence. Correlation functions and variances were obtained for the case of appreciable parent decay. Expressions for the average value and variance of the correlation function for a prompt daughter with appreciable parent decay were also obtained. A measurement of about 3% accuracy for daughter mean lives on the order of 0.1 sec during a period of one day can be achieved. General relations were developed for determining the daughter decay constant No measurable from experimental data for the correlation function using a weighted least squares criterion. (D.C.W.)
