    • Abstract


      A simplified method of determining the electron-neutral collision frequency at unit pressurev0 is presented in a number of gases (hydrogen, argon and air) in crossed electric and magnetic fields utilising the sparking voltage data and equivalent pressure concept. The values ofv0 for lowH/p are found to agree with those reported by other authors. But at highH/p, the estimated values ofv0 are appreciably higher for all the three gases. The increase in the values ofv0 possibly occurs due to the change of the electron energy distribution at higherH/p.
