    Atomic-scale study of the amorphous-to-crystalline phase transition mechanism in GeTe thin films 
    Mantovan, R.; Fallica, R.; Mokhles Gerami, A.; Mølholt, T. E.; Wiemer, C.; Longo, M.; Gunnlaugsson, Haraldur; Johnston, K.; Masenda, H.; Naidoo, D.; Ncube, M.; Bharuth-Ram, K.; Fanciulli, M.; Gíslason, Hafliði Pétur; Langouche, G.; Olafsson, Sveinn; Weyer, G. (Springer Nature, 2017-08-15)
    The underlying mechanism driving the structural amorphous-to-crystalline transition in Group VI chalcogenides is still a matter of debate even in the simplest GeTe system. We exploit the extreme sensitivity of 57Fe emission Mössbauer spectroscopy, ...

    Decay of muons generated by laser-induced processes in ultra-dense hydrogen H(0) 
    Holmlid, Leif; Olafsson, Sveinn (Elsevier BV, 2019-06)
    This work reports identification of muons by their characteristic life-time of 2.20 μs after laser-induction of their precursor mesons, both kaons K± and KL 0 and pions π± in ultra-dense hydrogen H(0). The pair-production signal from scattered muons ...
