The detailed analysis of the
-delayed fission data of
Tl is presented. The experiment was performed by producing a pure beam of
Tl by means of highly selective resonance laser ionization followed by mass separation with the ISOLDE isotope separator. A surprising asymmetric mass distribution of fission fragments from
Hg, the daughter of
Tl
decays, was obtained. Here, the energy calibration of the silicon detectors, which is crucial for a proper determination of the fission fragments' energy and mass split, is presented and the total kinetic energy and its dependence on the mass split ratio is discussed. A more precise
-delayed fission probability of 3.2(2)
10
was deduced.
