Abstract


In this thesis, on the basis of the fine structure theory and the theory of micro - Bo Seman effect of the non-relativistic atomic level structure calculations and multi-electron atoms , irreducible tensor theory and angular momentum coupling theory , a more systematic study of the helium atom 1s NP configuration Zeeman effect , including the the Zeeman Hamiltonian establishment , the Zeeman Hamiltonian ball tensor form , Zeeman Hamiltonian | LSJM_J gt ; representation matrix elements , and gives the energy levels of different magnetic field intensity division. Text is divided into five chapters , each chapter reads as follows: In the first chapter , are listed in this paper the use of the basic theory : angular momentum coupling theory of irreducible tensor theory , multi-electron atoms Zeeman Hamiltonian operator, and used to calculate the non-relativistic energy of helium atoms Ritz variational method , which takes into account the electronic exchange interaction and different levels of electronic shielding effect . In addition, given the helium atoms required by Chapter radial integral and g-factor four configuration parameters in the single-electron radial functions . In the second chapter , with angular momentum coupling theory of the multi-electron atoms Zeeman Hamiltonian (including a magnetic field , and secondary role ) All rewrite the ball tensor , this tensor the form of the advantages is that the Zeeman Hamiltonian operator has been in the radial, angular and spin part of the completely separate , so as to facilitate the use of irreducible tensor theory to calculate the Zeeman Hamiltonian matrix elements . In the third chapter , contains two parts , one is for n1l1n2l 2 configuration , the representation transformation theory , the theory of irreducible tensor and angular momentum coupling theory derived monomer - operator and multi - operator | LSJM_J GT ; the appearance matrix elements of the general expression ; second is the use of Zeeman Hamiltonian derived tensor form , for 1snp configuration further export helium original
