✦ Synopsis

Electron resonance gas phase transitions with a polarization paraUe1 to the externa! maSrwtic fietd are reported * in halogen atoms Atoms are produced inside the ESR cavity by means of a hot-wire method. 1. Introduction Electron resonance spectra of chlorine f l] , bromine [Z] and iodine [31 atoms in their 2P,,2 ground state have been reported. The observed transitions were alI of the type A&fJ = t 1, AMI = 0 in the high-field quantum number representation. They were induced by the magnetic component of the microwave tieId perpendi~~l~ to the external magnetic field. Transitions arising from the pa&e1 magnetic component of the microwave field have only been detected so far in fluorine atoms [4] _ En ail cases the atoms were produced by a rnicrowave discharge in a gas stream entering the ESR cavity.

We wish to report the detection of various "paraG transitions" in halogen atoms obtained by thermolysis.
