  The effect of detailed balance in induced gluon radiation for an energetic
parton propagating inside a quark-gluon plasma is discussed. The stimulated
thermal gluon emission reduces while absorption increases the parton's energy.
The net contribution results in a reduction of the effective parton energy
loss. The relative reduction of the parton energy loss is found to be important
for intermediate parton energies and negligible for very high energies. This
will increase the energy dependence of the parton energy loss and will affect
the shape of suppression of moderately high p_T hadron spectra.
