Heavy ion range anisotropy in muscovite mica

The anisotropy of heavy ion range in layered crystal of muscovite mica has been studied in the present investigation. The freshly cleaved basal plane of the natural muscovite mica has been irradiated with various energetic heavy ions with different dip angles from UNILAC (Universal Linear Accelerator) heavy ion accelerator, GSI, Darmstadt, Germany. We have tried to investigate the causes and effects of the anisotropic nature of the layered crystalline mica on heavy ions propagation. The measured and available range values of number of heavy ions [viz: 58Ni; 93Nb; 129Xe; 132Xe; 197Au; 208Pb; 209Bi; and 238U] in muscovite mica are used to highlight the shortcomings of various range and energy loss formulations about the orientation effect on stopping processes in anisotropic media.
