We present a new analytic treatment of two-electron integrals over two-center integrals including correlation (interelectronic distance) explicitly in the wave function. All the integrals needed for the evaluation of the matrix elements of any diatomic two-electron molecule are obtained as analytic recursion expressions. As an application of this method in molecular physics, we calculate the va...

Borrowing the structures of hydrogen atom, molecular ion, and diatomic molecule, we predict nature a new type hydrogenlike charm-pion or charm-kaon matter that could be obtained by replacing proton electron in with charmed meson pion kaon, respectively. We find spectra molecule can simultaneously Coulomb potential for hydrogen, charm-pion, systems. The predicted also allows us to explore mass s...

Resonance Raman scattering of light from a diatomic molecule" (1976). Resonance Raman scattering from a homonuclear diatomic molecule is considered in detail. For convenience, the scattering may be classified into three excitation frequency regions-off-resonance Raman scattering for inciderit energies well away from resonance with any allowed transitions, discrete resonance Raman scattering for...

A quantum kinetic theory of molecule formation is presented which includes three-body recombination and radiative association for a thermodynamically closed system which may or may not exchange energy with its surrounding at a constant temperature. The theory uses a Sturmian representation of a two-body continuum to achieve a steady-state solution of a governing master equation which is self-co...

The vibrational excitation cross-section of a diatomic molecule by positron impact is obtained using wave-packet propagation techniques. dynamics study was carried on two-dimensional potential energy surface, which couples hydrogenlike harmonic oscillator to via spherically symmetric correlation polarization potential. for the first mode in good agreement with previous reports. Our model sugges...
