Descrição: Use of a coincidence technique for registration of fragment ions and photoelectroms from dissociative ionization of molecules opens the possibility of studying the photoionization of oriented molecules in a gas phase. The first results obtained by this technique for O2 molecules are presented. The angular distribution of photoelectrons as a function of an angle between molecular axis and a photoelectron momentum is measured for the B2 SIGMA(g)- final ionic state using the HeI resonance radiation. From measured data it follows that the ratio of channel cross sections is sigma(sigma)/sigma(pi) = 0.67 +/- 0.08.
