Abstract
We present a combined experimental and theoretical study of the transient absorption spectroscopy of N2O at the N K edge (400 eV) by employing an attosecond soft x-ray pulse and an overlapping intense femtosecond infrared pulse. Our experiment demonstrates that tunnel ionization of the core-excited states of neutral N2O causes prominent half-cycle oscillations in the absorption signal. In addition, we observe the appearance of the N2O+ signal with increasing delay as a result of the tunneling ionization of N2O, thereby allowing us to follow the tunneling process in real time.We have developed theoretical models that allow us to interpret and reproduce the main trends of the experimental data.Citation
