  Configuration interaction in many-electron atoms may cause anomalies in the
fine structure which make the intervals small and very sensitive to variation
of the fine structure constant. Repeated precision measurements of these
intervals over long period of time can put strong constrain on possible time
variation of the fine structure constant. We consider the $5p^4 \
^3$P$_{2,1,0}$ fine structure multiplet in the ground state of neutral
tellurium as an example. Here the effect of change of the fine structure
constant is enhanced about one hundred times in the relative change of the
small energy interval between the $^3$P$_1$ and $^3$P$_0$ states.
