Abstract
GEIGER-MÜLLER counters filled with methylene bromide and argon are known1 to be self-quenching and to possess long sloping plateaux. Measurements have now been made of the β-counting-rate as a collimated source was moved diametrically across the mica end-window of a β-ray counter so that β-particles entered the counter parallel to the centre wire. Two counters A and B of identical construction were used for these measurements, A containing argon at a pressure of 97 mm. of mercury and ethyl alcohol at a pressure of 9·7 mm. of mercury, and B containing argon at a pressure of 7·4 mm. of mercury and methylene bromide at a pressure of 7·4 mm. of mercury. It was found that the efficiency of counter B was greatest for particles entering the counter near the centre wire, but even then was less than that of counter A by a factor of about three.
