| Abstract: | A dope concentration dependent quadrupole relaxation and a large anisotropy of the recoilles fraction are observed for substitutional iodine impurities in silicon, using 129I Mössbauer spectroscopy. The results are interpreted in terms of a transition from a static to a dynamic Jahn-Teller distortion. |
