State-selective charge exchange in slow collisions of Si3+ions with H atoms: A molecular state close coupling treatment*)

Charge transfer in slow collisions of H with Na

We reexamined charge-transfer cross sections for protons colliding with Na(3s) atoms for collision energies from the threshold at 1.7 eV to 40 eV using the recently developed hyperspherical close-coupling method. Our results disagree with the recent calculations by Dutta et al. @Phys. Rev. A 63, 022709 ~2001!#, but are in good agreement with the earlier calculations of Croft and Dickinson @J. P...

He-He charge transfer collisions using a 27-state close-coupled calculation with a diabatic molecular basis

A comparative study of two earlier three-state and fifteen-state [Chaudhuri et al., PramanaJ. Phys., 43, 175 (1994); ibid., Phys. Rev. A, 52, 1137 (1995)] close-coupled treatments of He-He single and double charge transfer collisions is made in this paper with a larger, 27-state close-coupled calculation. The calculations have been done using the diabatic molecular basis set used in the earlier...

Charge exchange in Li2+(1s) + H(ls) collisions. a molecular approach including two-electron translation factors

2014 We calculate the cross section for the charge exchange process in Li2+(1s) + H(1s) collisions, using an eight term molecular expansion that includes a two-electron common translation factor. The results are stable with respect to the variations of the parameters included in this translation factor. At low velocities (03BD 0.5 a.u.) the most important contribution to the total cross section...

Close-coupling study of rotational energy transfer of CO „ =2... by collisions with He atoms

Quantum close-coupling scattering calculations of rotational energy transfer in the vibrationally excited CO due to collisions with He atom are presented for collision energies between 10−5 and 1000 cm−1 with CO being initially in the vibrational level =2 and rotational levels j=0,1 ,4, and 6. The He–CO interaction potential of Heijmen et al. J. Chem. Phys. 107, 9921 1997 was adopted for the ca...
