Abstract

We study the mobility, K, of ions of both signs which are produced by α or β rays under atmospheric pressure.

For small ions (K > 1 × 10-4 m2 V-1 sec-1) and intermediate ions (1 × 10-4 > K > 1 × 10-5 m2V-1 sec-1) one obtains, using a low resolution, a continuous variation of K with water vapor content of the gas or with aging time.

The law of variation of K can be related to the attachment probability P of impurity molecules to the ion. With r being the radius of the ion, this probability is given by Pr -4.
