摘要

Background: Earlier measurements of fission lifetimes of the highly excited uraniumlike nuclei by K x-ray fluorescence and crystal blocking techniques obtained slow fission (fission time similar to 10(-18) s) for most of the fission events and were shown to be incompatible with the very short fission time (similar to 10(-20) s) obtained by the nuclear techniques and also with the very small (= 5%) percentage of such slow fission events predicted by simple statistical models. One weakness of the earlier fluorescence experiments is that the observed K x-ray peaks were very broad [full width at half maximum (FWHM) approximate to 15 keV] and the precise energies of the relevant K x-ray lines could not be determined from such measurements.
