摘要:
A comparison method of measuring, by using solutions, the capture cross-sections for thermal neutrons is described. The chief advantages are directness, simplicity, and freedom from uncertainties as to direction of path, or as to the magnitude of the scattering effect. The method is best suited to nuclei of large cross-sections. Assuming the well checked value for the cadmium nucleus to be correct, the capture cross-sections of certain other nuclei were determined. The results for barium and for hydrogen differ widely from values previously published.

摘要:
Starting with the elementary equation for the diffusion of a vapour, an equation is developed giving the relation between the amount of vapour diffusing through a slit in an impermeable membrane and the width of the slit. The results given by this equation are compared with experimental values and a satisfactory agreement is obtained.
