The recently observed -decay chain 108Xe 
104Te
100Sn (K. Auranen et al., Phys. Rev. Lett. 121, 182501 (2018)) could provide valuable information on the clustering in even-even nuclei slightly above the major shells 
and 
. In this work, this -decay chain is studied theoretically within the framework of the density-dependent cluster model plus the two-potential approach. We calculate the -decay half-lives of 104Te and 108Xe and study in detail their dependence on the Q value and the density-profile parameters of the core nucleus. Various physical properties of 104Te, the heaviest nucleus with a doubly magic self-conjugate core + , are calculated, with two different assumptions on the renormalization factor of the double-folding potential, which could be a useful reference for future experimental studies.
