Comments on a Proposal for Determining the Photon Mass

Abstract

It has recently been proposed by Franken and Ampulski that it may be possible to establish a new upper limit on the photon mass by means of measurements on an oscillating circuit with a frequency about 1 rad/sec. We show that the argument in this paper is in error, and that in reducing the size of their apparatus from the photon's conjectured Compton wavelength to table-top size the authors have lowered the sensitivity of their experiment by the same ratio.
