K-shell autoionization accompanying the beta decays of /sup 99/Tc, /sup 147/Pm, /sup 151/Sm, and /sup 204/Tl

; ;
The K-shell autoionization probabilities of /sup 99/Tc, /sup 147/Pm, /sup 151/Sm, and /sup 204/Tl have been determined to be (3.52 +- 0.20) x 10/sup -4/, (0.936 +- 0.063) x 10/sup -4/, (0.024 +- 0.003) x 10/sup -4/, and (1.22 +- 0.16) x 10/sup -4/, per decay, respectively. The first excited state branching ratios for /sup 147/Pm and /sup 151/Sm are (6.48 +- 0.56) x 10/sup -5/ and (0.94 +- 0.06) x 10/sup -2/, respectively. The K-shell electron capture to beta decay ratio for /sup 204/Tl is (1.22 +- 0.06) x 10/sup -2/. The autoionization probabilities are compared to the theory of Law and Campbell as modified by Isozumi, Shimizu, and Mukoyama.
