ABSTRACT
This chapter gives an account of experiments to throw further light on these points and to test whether any evidence of artificial disintegration can be observed in the case of other light elements. The microscope used for the counting of scintillations has been further improved. When the magnetic field was applied in such a way as to bend the α particles upwards the edge of the beam is deflected downwards in the field of the microscope and the scintillations appear only in the lower half. When the field was applied in the opposite direction the edge of the beam moved upwards in the field of view. The strength of the magnetic fields used in the experiments was always such that the whole field of view was covered with scintillations when the negative magnetic field was applied. In the experiments on the magnetic deflexion of the long-range particles, the number of particles is far too small to a band of scintillations.
