The breakdown potential in air in crossed electric and magnetic fields withtn the pressure range 10/sup -//sup 3/ to 1 mm of Hg was measured. The discharge was excited by a 10 kv transformer. The magnetic field was varied from 50 to 2000 gauss, and three discharge tubes of 9, 22.5, and 26.5 cm were used. From the measured breakdown potential data, the values of P/P were calculated using both Wehrli'a formula, and Bievin and Haydon's formula, where the magnetic field is taken as 100 gauss. From the curves obtained it can be concluded that both expressions for P/sub e/ are of limited applicability and the concept of equivalent pressure alone cannot explain all the observed results. It is hoped that the incorporation of variation of gamma with H along with equivalent pressure concept will explain the observed changes better. An expression of E/p is developed for this purpose.
