Title: Z and A identification of 370-. mu. s /sup 258/Fm

Journal Article · · Phys. Rev. C; (United States)

Correlation of time intervals between two modes of decay has been used to determine unequivocally the atomic and mass numbers of /sup 258/Fm, a nuclide which rapidly decays by spontaneous fission. We measured the time interval between the emission of Fm K x rays, due to electron capture by 60-min /sup 258/Md/sup m/, and the detection of fission fragments from the spontaneous fission of /sup 258/Fm to establish a genetic relationship and to determine the mean lifetime of /sup 258/Fm. We obtained a half-life of 360 +- 20 ..mu..s, which is in good agreement with our much earlier value of 380 +- 60 ..mu..s measured by another method.
