This surprising result has been explained by Engelsberg and Simpson /3/ who showed that the in- fluence of the electron-phonon interaction on the dHvA effect is rather subtle
Our low value for the activation energy of about O.leV which is comparable to that of irradiated pure LiNb03, /9/, suggests that the self trapped holes are thermally
Since the orbital functions of the spin singlet and the spin triplet states may differ, six parameters are needed to describe the electron- lattice interaction in

To afford a firm basis for the surface analysis by STM, it is indispensable to elucidate how the tunneling current is determined by the microscopic structure and
Our point of view is that a language with computational effect is a kind of language with an apparent lack of soundness: a language with computational effect is made of a syntax,
