Absolute double differential cross section measurements on the formation of the helium-like doubly-excited state of B³⁺(2p²)¹D are reported. The state is populated via the resonant electron transfer and excitation process in collisions of (3.5 - 8) MeV B⁴⁺ + H₂. A zero-degree high efficiency hemispherical spectrograph¹ was used to measure the Auger decay of the doubly-excited states to the B⁴⁺(1s) ground state. The measured Auger decay rates are compared to the theoretical predictions.
