An approximate analytical solution is developed for the distributions in energy and angle of positrons generated by fast electrons incident on a thick radiator (≈ 0.2 radiation lengths). For small angles, the positron energy spectrum may be express

Energy spectra from the reactions 28Si(γ, p)27Al and 28Si(γ, α)24Mg have been measured with good resolution (≈ 70 keV) by irradiating a silicon surface barrier detector with bremsstrahlung at a number of energies between 16.2 MeV and 23.2 MeV. T

The ultraviolet absorption cross-section for molecular hydrogen at room temperature has been measured absolutely at a resolution of 0·3 A, between 1060 and 1130 A. This range of wavelengths covers the (0-0) through (3-0) vibrational bands of the B1

Oscillator strengths for the (2, 0)-(20, 0) bands of the B3 Σ-u-X3 Σ-g Schumann-Runge system in molecular oxygen have been determined from absolute measurements of the absorption coefficient over the wavelength range 1700–2000 A. The measurements

Cross sections for the reactions Mo100(γ, n + γ, p), Mo98(γ, np), Mo97(γ, p), Mo92(γ, n) and Mo92(γ, 2n + γ, np) have been determined by activation methods for photon energies up to 33 MeV. The photoproton cross section, which exhibits a maxim

The independent fission yields of four fission products of U238 and three of Th232 photofission by thick-target bremsstrahlung of 23 MeV maximum energy, have been measured. The results are in general agreement with the proposal of equal charge displa

A broad absorption spectrum with λ max ⩾ 2000 nm has been observed in pulse-irradiated liquid propane at low temperatures, and assigned to the solvated electron. The electron decays by geminate recombination with an initial half-life of ⩽ 95 nse
