USING a powerful polonium source and an especially well-defined geometry, we have recently obtained 850 expansion-chamber photographs showing 90 proton tracks produced on the disintegration of nitrogen by ?-particle bombardment. Our arrangement, ther

New palaeomagnetic data from 106 14C-dated lava flows ranging in age from 200 to 31000 years b.p. yield an estimated angular dispersion value of 9.5°. These data and other new geological information permit a more precise estimate of the time interva

Using good diamond counters and variable electrode separations from 10μ up to 1 mm, a survey of the surfaces of several specimens allowed the selection of crystals with the most uniform behaviour. The variation of the characteristics of the (pulse h

The performance of diamonds as conduction counters is discussed. The main disadvantages are the continuous pulse height distribution, even with monoenergetic particles, and polarization phenomena which tend to reduce the pulse heights, although the l

1. Gordon has proved that the scattering of particles by an inverse square field is the same on the wave mechanics as on the classical theory. Mott has however shown, from consideration of the symmetry of the wave functions, that the scattering is qu

Two large diamonds S1 and S5, both of good optical quality, were subjected to β-irradiation and the electrical conduction responses were studied under a variety of conditions With S1 special attention was paid to the formation and removal of space c

Of the man conflicting experiments* which have been performed on the single scattering of fast β-particles by atomic nuclei, it is generally accepted that the most reliable are those of Chadwick and Mercier, and of Neher. The former experimenter use

A combined arrangement of counters and a cloud chamber is used to examine the elastic large-scale scattering of β-particles of approximately 1 MeV. energy by nitrogen nuclei. In a total effective track length of nearly 100 km., 131 photographs were

Using the concept of the defect bond, which is somewhat analogous to the covalent bond, a qualitative theory of the physical properties of pure diamond is developed. The theory allows an explanation of many of the diverse physical properties of diffe

The present paper gives an account of measurements on some close collisions of fast β-particles with electrons, photographed by the Wilson cloud method. These measurements afford a direct test of the applicability of the principles of the conservati
