The spontaneous resonance emission of CH3I in high pressures (800â€“1600 psi) of CH4 and Ar excited in the region of the Rydberg B-state origin (âˆ¼201 nm) are reported. These emission spectra consist of narrow Raman-like (RL) and broad fluorescence-like (FL) spectral features. The...

An exact expression for the atomic form factor for closed shell atoms is derived using an antisymmetric multielectron wave function. It is shown that for large atoms it can be written as an integral over a Bessel function. Using the Hankel transform it gives an expression for the density of...

We have recently presented a formalism for calculating zero-point vibrational corrections to molecular properties of polyatomic molecules in which the contribution to the zero-point vibrational correction from the anharmonicity of the potential is included in the calculations by performing a...

A modified perturbation approach for the calculation of the vibrational wave function of polyatomic molecules is discussed. It is demonstrated that if the expansion point of the potential is determined variationally, the leading first-order term in the perturbation expansion of the vibrational...

Wave functions of excited, ionized, and electron attached states are produced by applying the excitator method to the mixed-exponentially generated (MEG) wave function for a ground state. This method is called excited-(EX-)MEG method and the computational algorithm is summarized. The MEG/EX-MEG...

We continue to study exponential ansatz as a candidate of the structure of the exact wave function. We divide the Hamiltonian into N[sub D] (number of divisions) parts and extend the concept of the coupled cluster (CC) theory such that the cluster operator is made of the divided Hamiltonian....
