===<sup>268</sup>Mt===
The alpha decay spectrum for <sup>268</sup>Mt appears to be complicated from the results of several experiments. Alpha lines of 10.28,10.22 ans 10.10 MeV have been observed. Half-lives of 42 ms, 21 ms and 102 ms have been determined. The long-lived decay is associated with alpha particles of energy 10.10 MeV and must be assigned to an isomeric level. The discrepancy between the other two half-lives has yet to be resolved. An assignment to specific levels is not possible with the data available and further research is required.
