The frequency of occurrence of cosmic-ray bursts under large thicknesses of lead and iron has been measured as a function of the thickness, using a small ionization chamber with and without shielding material round its sides. Experiments have also be

Detailed analysis of phase-amplitude curves is found to provide much insight into the elastic scattering of heavy ions at intermediate and high energies, where numerical calculations become lengthy. The nuclear interaction is first treated by the str

Consideration of the effect of target polarization is extended to inelastic collisions. The accuracy of the usual methods of obtaining polarization potentials by the implicit use of perturbation theory is found to be poor, as tested on hydrogen by th

For direct nuclear reactions in which there is a large probability of a particular inelastic collision, coupling between the waves in the two channels will modify the elastic and inelastic scattering as given by the distorted wave approximation. The

The scattering of electrons by gold, xenon and krypton atoms has been investigated using Dirac’s equations. The polarization to be expected by double scattering at 90° has been studied for an energy range 100 to 150.000 eV. The results agree subst

The quantum theory has provided a means of calculating the interaction energies of two atoms by a perturbation method. It appears that, the short range interaction forces are due mainly to electron exchange phenomena between the two atoms, while the

One of the outstanding differences between classical theory and quantum mechanics is the importance which the latter attaches to the identity of particles. Although perfectly well realised before the introduction of modern quantum theory, the fact th

Although a satisfactory theory of the collisions of fast electrons with atoms is provided by the method of Born-Dirac, a complete theory of slow collisions has not yet been developed. This is due to the large number of complicating factors which cann

The collision of a slow moving electron with an atom is known to be a very complicated phenomenon involving a number of processes which are themselves complex. To obtain even an approximate description of such phenomena the only method of attack is t

During the last few years there has been a great increase in experimental knowledge of the properties of the lighter nuclei. Whereas the proton and the α-particle were the simplest nuclei known in 1931, we are now familiar with some properties of th
