The half-lives of the 14.4 keV isomeric state in {sup 57}Fe and the 9.4 keV isomeric state in {sup 83}Kr have been accurately measured using electronic timing. The two isomers were populated in the electron capture decays of {sup 57}Co and {sup 83}Rb, and the time distributions between {gamma}-{gamma} cascades proceeding via the isomers were determined. Results are 99.2(4) and 155.1(12) ns for the {sup 57}Fe and {sup 83}Kr states respectively.
