    Control of photoemission delay in resonant two-photon transitions
    (Bristol : IOP Publ., 2017) Argenti, L.; Jiménez Galán, Á.; Taïeb, R.; Caillat, J.; Maquet, A.; Martín, F.
    Synopsis In contrast to one-photon transitions and non-resonant multiphoton transitions, time delay in resonant multi-photon electron emission can exhibit large positive and negative values that have no scattering equivalent, due to the interference of multiple ionization paths.

    Evidence for Efficient Pathway to Produce Slow Electrons by Ground-state Dication in Clusters
    (Bristol : IOP Publ., 2017) You, Daehyun; Fukuzawa, Hironobu; Sakakibara, Yuta; Takanashi, Tsukasa; Ito, Yuta; Maliyar, Gianluigi G.; Motomura, Koji; Nagaya, Kiyonobu; Nishiyama, Toshiyuki; Asa, Kazuki; Sato, Yuhiro; Saito, Norio; Oura, Masaki; Schöffler, Markus; Kastirke, Gregor; Hergenhahn, Uwe; Stumpf, Vasili; Gohkberg, Kirill; Kuleff, Alexander I.; Cederbaum, Lorenz S.; Ueda, Kiyoshi
    We present an experimental evidence for a so-far unobserved, but potentially very important step relaxation cascades following inner-shell ionization of a composite system: Multiply charged ionic states created after Auger decay may be neutralized by electron transfer from a neighboring species, producing at the same time a low-energy free electron. This electron transfer-mediated decay (ETMD) called process is effective even after Auger decay into the dicationic ground state. Here, we report the ETMD of Ne2+ produced after Ne 1s photoionization in Ne-Kr mixed clusters.

    Intracycle interference in ionization of Ar by a laser assisted XUV pulse
    (Bristol : IOP Publ., 2017) Arbó, D.G.; López, S. D.; Kubin, M.; Hummert, J.; Vrakking, M.J.J.; Kornilov, O.
    Synopsis We present a theoretical and experimental study of the subcycle interference in laser assisted XUV ionization of Ar atoms. Averaging over the focal volume happens to blur the intracycle interference, which thus cannot be measured directly. We show that even at these conditions, the intracycle interference can be obtained through the subtraction of two different angle and energy-resolved distributions at slightly different laser intensities.
