摘要：

Angular distributions of the two ejected electrons following photodouble ionization of molecular deuterium have been measured using a toroidal photoelectron-photoelectron coincidence spectrometer in conjunction with synchrotron radiation. Six (gamma,2e) triple differential cross sections (TDCS) were measured in the plane orthogonal to the photon beam direction with E-1 = E-2 = 10 eV. The angular distributions are similar to those of helium, but with differences which we highlight by comparing the D-2 TDCS with helium TDCS measured under nearly identical conditions.
