    The association of hydrogen with nanometre bubbles of helium implanted into zirconium by Blackmur, MS, Dumbill, S, Maclaren, I, Hernandez-Maldonado, D, Styman, PD, Gass, M, Nicholls, RJ, Hyde, JM, Ramasse, QM, Annand, KJ, Smith, JS, Gotham, N

    Published 2018
    “…Electron energy-loss spectroscopy (EELS) is used to investigate the association of hydrogen with helium bubbles in zirconium. Conventional EELS data yield a signal at 13.5 eV (similar to the hydrogen K-edge, 13 eV), which is spatially distributed around the peripheries of bubbles and may correlate with the concentration of hydrogen/deuterium in the material. …”

    Orientation-dependent indentation response of helium-implanted tungsten by Das, S, Yu, H, Tarleton, E, Hofmann, F

    Published 2019
    “…The results suggest that the mechanism governing the interaction of helium-induced defects with glide dislocations is orientation independent. …”

    Study of Helium Swelling and Embrittlement Mechanisms in SiC Ceramics by Kymbat M. Tynyshbayeva, Kayrat K. Kadyrzhanov, Artem L. Kozlovskiy, Yerzhan I. Kuldeyev, Vladimir Uglov, Maxim V. Zdorovets

    Published 2022-02-01
    “…It has been established that the greatest changes in the strength properties are associated with the dominance of the crystal lattice swelling effect in the structure due to an increase in the concentration of implanted helium, and its further agglomeration with the formation of vacancy complexes of the He-V type. …”

    Role of electron wavepacket interference in the optical response of helium atoms by Matteo Lucchini, Jens Herrmann, André Ludwig, Reto Locher, Mazyar Sabbar, Lukas Gallmann, Ursula Keller

    Published 2013-01-01
    “…Attosecond control of the optical response of helium atoms to extreme ultraviolet radiation in the presence of moderately strong infrared laser light has been recently demonstrated both by employing attosecond pulse trains (APTs) and single attosecond pulses. …”

    Characteristics of Plasma Dynamics in Current Sheets Formed in Helium Plasma by Anna G. Frank, Natalya P. Kyrie, Sergey N. Satunin, Sergey A. Savinov

    Published 2021-10-01
    “…The characteristic features of plasma acceleration in the current sheets are discussed on the basis of an analysis of the structure of electrodynamic forces at successive stages of the evolution of the current sheets formed in the plasma with helium ions. Of particular interest is the generation of reverse currents at the side edges of the sheet and the appearance of forces, which are braking previously accelerated plasma flows.…”
