Abstract
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 $(\ensuremath{\gamma},2e)$ triple differential cross sections (TDCS) were measured in the plane orthogonal to the photon beam direction with ${E}_{1}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}E}_{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}10\mathrm{eV}$. The angular distributions are similar to those of helium, but with differences which we highlight by comparing the $\mathrm{D}{}_{2}$ TDCS with helium TDCS measured under nearly identical conditions.
