Properties of the mitibule

JUN 01, 1950

Very few physicists in the United States have been aware of the sub‐atomic particle described below, knowledge of its existence being limited in large part to the audience of the February 1950 issue of the Bulletin of the Canadian Association of Physicists, from whose pages it is reprinted here.

Evidence in support of this new sub‐atomic particle was first found by A. G. Ratz and W. J. Weir in the spring of 1944 at the University of Toronto (Phys. Rev. 66: 366, 1944). Owing to the exigencies of wartime, work on the project was suspended for almost three years. At the present time the mass and charge, if any, of the particle have still not been ascertained with any degree of accuracy, but it is felt that the discovery is likely to prove so important, and so worthy of attention, as to warrant a review of our present knowledge of the particle, in spite of the lack of reliable quantitative measurements. The difficulties in the way of experiments with mitibules will be apparent from the discussion.
