英文摘要	Two-layer monoclinic (2M) muscovite mica sheets with a thickness of 12 mu m are irradiated with Sn ions at room temperature with electronic energy loss (dE/dx)(e) of 14.7 keV/nm. The ion fluence is varied between 1 x 10(11) and 1 x 10(13) ions/cm(2). Structural transition in irradiated mica is investigated by x-ray diffraction (XRD). The main diffraction peaks shift to the high angles, and the inter-planar distance decreases due to swift heavy ion (SHI) irradiation. Dehydration takes place in mica during SHI irradiation and mica with one-layer monoclinic (1M) structure is thought to be generated in 2M mica after SHI irradiation. In addition, micro stress and damage cross section in irradiated mica are analyzed according to XRD data. High resolution transmission electron microscopy (HRTEM) is used on the irradiated mica to obtain the detailed information about the latent tracks and structural modifications directly. The latent track in mica presents an amorphous zone surrounded by strain contrast shell, which is associated with the residual stress in irradiated mica.
