Item The Influence of Crystal Field and Induced Magnetic Moments on Current and Magnetization Densities(AL-Neelain University, 2010) AMANI SALAH MOHAMMEDItem THE MAGNETIC FIELD GENERATED BY TWO ELECTRONS BOUND IN SOME AN GULAR MOMENTUM EIGENSTATES(Neelain University, 2003) AMANI SALAH MOHAMMEDAbstract Application of a direct general method for calculating the magnetic field gen- erated by two electrons bound in angular momentum eigenstates is presented, illustrated and applied to the ground states of the tripositive ions Pr“ and V3+. The ground state wave functions are written as a four components spinor and the operators for the orbital current and spin densities as a 4 x 4 matrices. Analytical expressions for the expectation values of these opera- tors are presented by making use of hydrogenic wave function. The resulttent expressions of the current densities are substituted in the components of the magnetic field which gives unexpected results. 7Item THE MAGNETIC FIELD GENERATED BY TWO ELECTRONS BOUND IN SOME ANGULAR MOMENTUM EIGENSTATES(Al Neelain University, 2003-03) AMANI SALAH MOHAMMEDApplication of a direct general method for calculating the magnetic field gen- erated by two electrons bound in angular momentum eigenstates is presented, illustrated and applied to the ground states of the tripositive ions Pr“ and V3+.
