【 摘 要 】

Synopsis We investigate bichromatic photoionization of neon induced by linearly polarized XUV femtosecond pulses. The fundamental frequency is tuned near an optically allowed transition to create an interference between one-photon and two-photon ionization pathways. The asymmetry in the photoelectron angular distribution is analyzed for a variety of pulse characteristics.
