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…
The two-dimensional hydrogen atom in The momentum representation
Mehdi Hage-Hassan
The analytic expression of the momentum representation in terms of the associated Legendre function is determined by a direct integration of Fourier transform of the wave function…
On the hydrogen wave function in Momentum-space, Clifford algebra and the Generating function of Gegenbauer polynomial
Mehdi Hage-Hassan
Using the quadratic transformation and the generating function method we Perform the Fourier transformation of the wave function of coordinates of hydrogen atom and we find the ana…
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…
