An account has recently been published by Dr. J. A. Crowther and the writer, of some experiments on the scattering of β-rays by thin sheets of matter. The angles of deflection investigated ranged from 4° to 8°. The main results obtained may be summarised as follows:— (1) The scattering observed was “single,” i. e., due to one collision with an atomic nucleus. (2) The law of force governing such collisions appeared to be that of the inverse square.
