… Since Q does not differ appreciably from unity unless O~/T) 1, we see that M increases ap…
At absolute zero, however, M does not vanish because of the zero point vibrations of the lattice. …

… If M and m are arbitrary operators belonging to the firstand second systems, respectively,
they … separate equations for the operators M and m, we find that our result has the structure …

… The factor 1/ e (where e = dielectric constant at the optical frequency involved) appears
because the transition probability is of the form 1 M . E 12 and the electric field whose energy …

… for which the right-hand mass M ’ is displaced to the right, say, the left-hand mass M’ is
displaced an equal amount to the left, and the center mass M is at equilibrium. This particular …

In a previous paper, the authors have developed a general theory of stochastic transport in
disordered systems. In the present paper, the theory is applied, in detail, to a prototype of …

Enormous capture cross sections in the range 10− 15 cm 2 to 10− 12 cm 2 have been
observed for a wide variety of Coulomb attractive centers in Si and Ge, some involving binding …

… we must take into account the fact that m is a function of i F)' and it must be expanded in powers
… where m, is the term of order f' in the expansion of m. If we solve (3.for E&' and substitute …

In connection with a study of laser-induced degradation of light-emitting semiconductor
material by a temperature rise, it was necessary to determine the temperature rise induced by a …
