Title Attosecond Strobing of Two-Surface Population Dynamics in Dissociating H2+
Abstract Using H2+ and D2+, we observe two-surface population dynamics by measuring the kinetic energy of the correlated ions that are created when H2+ (D2+) ionize in short (40?140 fs) and intense (1014 W/cm^2) infrared laser pulses. Experimentally, we find a modulation of the kinetic energy spectrum of the correlated fragments. The spectral progression arises from a hitherto unexpected spatial modulation on the excited state population, revealed by Coulomb explosion. By solving the two-level time-dependent Schro┬Ędinger equation, we show that an interference between the net-two-photon and the one-photon transition creates localized electrons which subsequently ionize.
