Generalization of Cramer's rule and its application to the projection of Hartree-Fock wave function
Mehdi Hage-Hassan
We generalize the Cramer's rule of linear algebra. We apply it to calculate the spectra of nucleus by applying Hill-Wheeler projection operator to Hartree-Fock wave function, and t…
On the N-dimensional hydrogen atom in momentum representation
Mehdi Hage-Hassan
We derive the wave function for N-dimensional hydrogen atom in the momentum representation with the phase factor using the generating function method and Hankel's integral.
Angular momentum and the polar basis of harmonic oscillator
Mehdi Hage-Hassan
In this paper we follow the Schwinger approach for angular momentum but with the polar basis of harmonic oscillator as a starting point. We derive by a new method two analytic expr…
On the Euler angles for the classical groups, Schwinger approach and Isoscalar factors for SU (3)
Mehdi Hage-Hassan
We establish recurrences formulas of the order of the classical groups that allow us to find a generalization of Euler's angles for classical groups and the invariant measures of t…
