The elastic collision of two H-like atoms including the exotic Ps and Mu
Hasi Ray
The elastic collision between two H-like atoms utilizing an ab-initio static-exchange model (SEM) in the center of mass (CM) frame considering the system as a four-body Coulomb pro…
The dependence of scattering length on van der Waals interaction and on the reduced-mass of the system in two-atomic collision at cold energies
Hasi Ray
The static-exchange model (SEM) and the modified static-exchange model (MSEM) recently introduced by Ray [1] is applied to study the elastic collision between two hydrogen-like ato…
The collision between positronium (Ps) and muonium (Mu)
Hasi Ray
The collision between a positronium (Ps) and a muonium (Mu) is studied for the first time using the static-exchange model and considering the system as a four-center Coulomb proble…
The collision between two ortho-Positronium (Ps) atoms: a four-body Coulomb problem
Hasi Ray
The elastic collision between two ortho-positronium (e.g. S=1) atoms is studied using an ab-initio static-exchange model (SEM) in the center of mass (CM) frame considering the syst…
The collision between two hydrogen atoms
Hasi Ray
The electron-electron correlation term in two-atomic collision is the most important, most difficult term to obtain the effective interatomic potential. Generally the H and H colli…
The Effect of van der Waals interaction in Elastic Collision between Ps(1s) and H(1s)
Hasi Ray, Anuradha De, Deparpita Ray
The modified static exchange model (MSEM) recently introduced by Ray [1] to study two-atomic collision processes at low and cold-energies, is used for detailed analysis of the long…
