Abstract
State to state rotationally inelastic and elastic differential cross-sections for the system D2CO-H2 have been measured at a center of mass energy of 17 meV. A single rotational state of D2CO (110) of high state purity is focused into the scattering region by combining rotational cooling and electric state selection. The final rotational state is probed angle dependent by LIF using a frequency doubled CW ring dye laser at 325 nm. The full range of CM angles is probed. We present the first results of the 110 → 111 inelastic scattering.
