Although a good deal of information is available related to the application of unitary group in physics, but they are restricted by difficult mathematics. Present work focuses on the use of permutation and unitary group techniques in the derivation .of wave functions for a system having two electrons in the valence f-shell. Slater determinantal, permutation and unitary group procedures have been developed to calculate these wave functions. An isomorphism between permutation group and Icosahedral poin~ group has been defined. After introducing the crystal field theory, A unitary group approach has been presented for the study of strong Icosahedral crystal fields  Supervisor : Dr. Mohammad Saeed Alahmadi  Thesis Type : Master Thesis  Publishing Year : 1422 AH 2001 AD  Co-Supervisor : Prof. Khursheed Athar Siddiqui  Added Date : Wednesday, June 11, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email وجود أحمد ديري Diery, Wajood Ahmed Researcher Master wdairy@kau.edu.sa Files File Name Type Description  23852.pdf pdf المستخلص  23853.pdf pdf Abstract Back To Researches Page
