We studied the relaxation behavior of crystal-field transitions
in the heavily overdoped high-temperature superconductor
(
) by neutron spectroscopic experiments. There is clear
evidence for the opening of the pseudogap at
and
for the
and
compound, respectively.
The fact that the pseudogap phenomenon extends far into the
overdoped region supports the theoretical view of the existence
of preformed pairs at
.
