| Description | Journal: Journal of Physics B: Atomic and Molecular Physics In the range of excitation energies from 26 to 40 eV there is evidence for the existence of resonant autoionising Rydberg states in $D_{2}(H_{2}$). In a 'photoionisation' experiment, using fast electron scattering at zero degrees, the authors have studied the dissociative decay of these states, leading to energetic $D^{+}(H^{+}$) fragments. After extraction by a strong field a time-of-flight analysis was made of all fragments emitted over 4 pi , in a photon energy range between 18 and 40 eV. This enabled them to determine partial oscillator strengths for contributions from the 1s sigma$ _{g}$, 2p sigma$ _{u}$ and Rydberg states. The absence of an isotope effect between $D_{2}$ and $H_{2}$ for the repulsive states under study shows that for these states there is no competition with decay modes other than autoionisation. As a function of photon energy, they find contributions from different Rydberg states leading to fragments with a kinetic energy distribution centred around 3 eV at 28 eV, and around 1 eV at 35 eV photon energy. |
