| 英文摘要 | studying the interaction of molecular nitrogen with extreme ultraviolet (xuv) radiation is of prime importance to understand radiation-induced processes occurring in earth's upper atmosphere. in particular, photoinduced dissociation dynamics involving excited states of n-2(+) leads to n and n+ atomic species that are relevant in atmospheric photochemical processes. however, tracking the relaxation dynamics of highly excited states of n-2(+) is difficult to achieve, and its theoretical modeling is notoriously complex. here, we report on an experimental and theoretical investigation of the dissociation dynamics of n-2(+) induced by isolated attosecond xuv pulses in combination with few-optical-cycle near-infrared/visible (nir/vis) pulses. the momentum distribution of the produced n+ fragments is measured as a function of pump-probe delay with subfemtosecond resolution using a velocity map imaging spectrometer. the time-dependent measurements reveal the presence of nir/vis-induced transitions between n-2(+) states together with an interference pattern that carries the signature of the potential energy curves activated by the xuv pulse. we show that the subfemtosecond characterization of the interference pattern is essential for a semiquantitative determination of the repulsive part of these curves. |
