(GAMMA,2E) CROSS-SECTION MEASUREMENTS OF D-2 AND HE

Angular distributions of the two ejected electrons following photodoub le ionization have been measured for molecular D-2 and He with E-1 = E -2 = 10 eV. The results were obtained at the Daresbury Synchrotron Rad iation Source using a multicoincidence spectrometer consisting of two toroidal analysers. The measured distributions show strong similaritie s, as well as differences which suggest that molecular effects are man ifest at these energy conditions.
