  A theoretical model involving phonon and lochon (local charged boson)
mediated pairing of electrons in Pd(H/D)x is suggested to explain the possible
observation of superconductivity in the range 51K < Tc < 295K (when x exceeds
unity). In the combined mechanism the lochons have transient existence on
(H+/D+) resulting in (H-/D-) species. The coupling parameter lambda_1 for
lochon induced processes depend linearly on x. The model explains the
observation of the enhancement of Tc for x varying from 0.6 to 1.6. While the
experimental observations are of great importance, it is desirable that other
experimental groups confirm the results.
