Extract

No satisfactory formula has so far been derived theoretically for the photoelectric absorption of X-rays and γ-rays. The empirical law

has hitherto been generally accepted as giving approximately the variation of the photoelectric absorption coefficient per electron, with atomic number Z and wave length λ for X-rays of wave length greater than 100 X.U., and the validity of this law has often been assumed for γ-rays also.

The recorded experimental data are the ionisation currents, with and without the absorber in position, for 8 degrees of filtering between 0.3 and 1.84 cm. together with the natural activity of the chamber. The filter curve has been reconstructed for each element and the absorption co-efficient determined by graphical methods.
