Rainbows with a < 111 > Si thin crystal

This study is devoted to the transmission of Ne10+ ions through a (111) Si thin crystal. The ion energy in 60 MeV and the crystal thickness is varied from 159 to 478 atomic layers, i.e., within the first rainbow cycle. The an alysis is performed by the theory of crystal rainbow. The angular distribut ion of the transmitted ions is generated by the computer simulation methods . Then, the rainbow lines in the scattering angle plane are determined. The se lines ensure the full explanation of the angular distribution .
