Quenching of -H with an ultra-cold anti-hydrogen atom
Renat A. Sultanov, Sadhan K. Adhikari, Dennis Guster
In this work we report the results concerning calculations for quantum-mechanical rotational transitions in molecular hydrogen, H, induced by an ultra-cold ground state anti-hy…
Low-energy muon-transfer reaction from hydrogen isotopes to helium isotopes
Renat A. Sultanov, Sadhan K. Adhikari
Direct muon transfer in low-energy collisions of the muonic hydrogen H and helium (He) is considered in a three-body quantum-mechanical framework of coordinate-space int…
Low-energy direct muon transfer from H to Ne, S and Ar using two-state close-coupling approximation to Faddeev-Hahn-type equation
Renat A. Sultanov, Sadhan K. Adhikari
We perform three-body calculation of direct muon-transfer rates from thermalized muonic hydrogen isotopes to bare nuclei Ne, S, and Ar employing integro-dif…
S-, P- and D-wave resonances in positronium-sodium and positronium-potassium scattering
Sadhan K. Adhikari, Puspajit Mandal
Scattering of positronium (Ps) by sodium and potassium atoms has been investigated employing a three-Ps-state coupled-channel model with Ps(1s,2s,2p) states using a time-reversal-s…
Convergent variational calculation of positronium-hydrogen-atom scattering lengths
Sadhan K. Adhikari, Puspajit Mandal
We present a convergent variational basis-set calculational scheme for elastic scattering of positronium atom by hydrogen atom in S wave. Highly correlated trial functions with app…
Differential cross sections for elastic and inelastic positronium-hydrogen-atom scattering
Sadhan K. Adhikari
We report results of differential cross sections for elastic scattering, target-elastic Ps excitations and target-inelastic excitation of hydrogen in a five-state coupled-channel m…
