The effect of the valence state of the tin atoms on the probability of radioactive decay has been studied by the ..delta..lambda/lambda and ..delta..I/I methods for the case of the isomeric M4-transition in the nucleus of tin-117m. The two methods gave concordant results: lambda(SnC/sub 2/O/sub 4/ x 2H/sub 2/O)-lambda(SnO/sub 2/) = + (7.5 +/- 1.5) x 10/sup -4/ x anti lambda; I (Sn(II) solution) - I (Sn(IV) solution) = + (7.0 +/- 1.0) x 10/sup -4/ x anti I. The values of the measured effects correspond, according to our estimates, to an overall decrease in electron density on the tin nucleus of 90 atomic units on transition from tin (II) to tin (IV).
