Abstract : It can be seen that for f = 69.9 kmc the observed resonance at H = 6.6 kilo-orsted corresponds to a polaron mass m*/m sub e = 0.27 in good agreement with the recent theory of Feynman et al. Although the agreement may be partly fortuitous, it seems to argue for the Froehlich model and approximations used by these authors, at least for small coupling constants. The theoretical mobility versus effective mass curve is such that a 10% error in the experimental mobility gives rise to an uncertainity of about 6% in m/m sub e. From the numbers it appears that the Low-Pines theory can be brought into closer agreement by improving the approximation m*/m = 1 + alpha/6. (Author)
