## Title

- title: Metallic Ca Aggregates Formed Along Ion Tracks and Optical Anisotropy in
    CaF2 Crystals Irradiated with Swift Heavy Ions

## Description

- description: 'It is known that swift heavy ion (SHI) irradiation induces shape elongation
    of metal nanoparti-cles (NPs) embedded in transparent insulators, which results
    in anisotropic optical absorption. Here, we report another type of the optical
    anisotropy induced in CaF2 crystals without including in-tentionally embedded
    metal NPs. The samples were irradiated with 200 MeV Xe^14+ ions with an incident
    angle of 45 deg from the surface normal. With increasing the fluence, an absorption
    band at ~550 nm, which is ascribed to Ca-aggregates, increases both the intensity
    and the anisotropy. XTEM observation clarified the formation of the continuous
    line-structures and the discontinu-ous NP chains parallel to the SHI beam. '
