A theoretical model for the JT effect describing this situation is presented. The model includes parameters for the energy differences between molecular terms that arise from Coulomb interactions between the holes. Although the magnitudes of these parameters are not known to any degree of certainty for the C60 2+ cation, they are likely to have an important effect. Results are given for both the static JT effect, where the motion of the system can be considered in terms of vibrations in a potential well, and the dynamic JT effect, where tunneling between equivalent wells must be taken into account.  ISSN : 1098-0121  Journal Name : Physical Review B - Condensed Matter and Materials Physics  Volume : 76  Issue Number : 8  Publishing Year : 1428 AH 2007 AD  Article Type : Article  Added Date : Wednesday, December 21, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email Ian D Hands Hands, Ian D Researcher Doctorate   وجود أحمد ديري Diery, Wajood A Researcher Doctorate wdairy@kau.edu.sa Colin A Bates Bates, Colin A Researcher Doctorate colin.bates@nottingham.ac.uk Janette L Dunn Dunn, Janette L Researcher Doctorate janette.dunn@nottingham.ac.uk Files File Name Type Description  31714.pdf pdf Abstract Back To Researches Page
