A few elementary results of Dirac's relativistic theory of the particle with the spin larger than 1/2 were deduced. Namely, the expressions for the velocity, the current density, the spin angular momentum and the electric and magnetic moments, which had not been given explicitly in Dirac's paper, were obtained. It is noticeable that the spin and the magnetic moment are not proportional to each other in general. The invariance of the wave equations under reflection (Spiegelung) was also discussed

The general formula representing the singlet and the triplet system of He is calculated using Breit's Hamiltonian. The interac'ion between the ringlet and the triplet system, and the polarisation effect of the outer electron on the inner electron are taken into account. The numerical separations of the triplet terms 1s2p

Relative cross suctions of 41 elements for gamma-ray excitation by neutrons of 2.4 m c v. energy were determined. Plotted against the atomic number of elements, they distribute near a smooth curve which rises with atomic number in the region of lower atomic number and probably falls again at the heaviest stable elements The energies of the gamma-rays were determined in 11 elements by the method of coincidence of two thin wallet Geiger-Muller counters. The absorption curves of the secondary electrons were different from element to element, showing that the spectra of gamma-rags are different. But no gamma-rays were observed whose energies exceed 2.4 m e. v. Thus it is very probable that the gamma-rays are phosphorescence gamma-rays excited by neutrons. The cross sections for the excitation of gamma-rays are compared with those for absorption of neutrons awl also fur the production of slow neutrons by the passage of neutrons through the matter

The problem of the neutron-reuteron collision was reduced to a simple form by taking the structures of
2II and
3II into account and neglecting the forces depending explicitly on the spin. (§1.) The form of the effective potential hole was determined by comparing the estimated value of the cross section of scattering of slow neutrons by deuterons with that obtained experimentally The cross section of capture was found to be small in agreement with the experiment The energy dependence of the scattering cross section was also discussed. (§2) The theory of Fermi concerning the effect of the chemical binding on the scattering of slow neutrons was extended to more general case and a necessary limitation of the theory was discussed. The eross section for thermal neutrons was found to he nearly twice as large as that for neutrons of several volts. (§3) Theoretical reasons for the small contribution of the deuteron to the slowing down were considered. (§4)
