A refined technique is described for approximating the numerically given radial part of atomic wave functions associated with self-consistent fields with exchange by means of Slater's analytical functions obtained by replacing each exponential in a hydrogen-like wave function by the sum of one,...
The correction to the Bethe-Bloch formula for the stopping power of fast heavy particles, due to virtual photons and the emission of real photons, has been computed using the Born approximation for the extreme relativistic case. The fractional correction increases with increasing energy of the...
Using the light absorption method, the duration of the P 2 3 metastable level of neon has been measured as a function of pressure at the temperatures of boiling water, ice, dry ice-alcohol, and liquid nitrogen. At pressures below 1 mm of mercury departure from Zemansky's formula is found only at...
The integral equation for the scattering of an electron from a symmetric diatomic molecule is solved approximately to obtain the effective interaction integral between the electron and the molecular vibrationrotation, neglecting polarization and exchange. This interaction depends on the...
Using as primary excitants ultraviolet light and polonium alpha-particles, the phosphorescent afterglow of the double banded phosphor, silver-activated sodium chloride, has been measured as a function of the time with photosensitive Geiger counters and photomultiplier tubes. The decay curves of...
The relative rates of local neutron production in Al, Cu, Sn, and Pb were obtained at geomagnetic latitudes λ = 40 ° and 54 ° at atmospheric depth 312 g- cm - 2 (30 000 ft pressure altitude). The latitude and altitude dependence of local neutron production in carbon and lead were measured in...
