the arrangement with which the intensity was found in air *) the ionisation was determined in argon at pressures between 38 and 1 atm.' under layers of 12 cm Fe and under 56 cm Fe. The intensity reduced to the value for one atmosphere is 1,58 I, under 12 cm Fe and 1.46 under 56 cm Fe. The energy of the electrons ejected from the iron walls is less under 56 cm Fe (max. 45 cm) than under 1'2 cm Fe (max. 54 cm).

The ionisation of argon due to cosmic and radioactive rays was investigated up to a pressure of 100 a{m The ionisation d u e to particles originating in the gas under the action of the incident radiation was separated from the portion which is due to particles emitted by the wall. By the incident r
According to our present, more accurate, method we find for photon shocks" fxP f (C + X P)" = 0,30 for X = 0,03 and 0,31 for X = 0,06, integrating over the whole hemisphere.
