B. Herrero et al., LOW-ENERGY-ELECTRON CAPTURE FROM H AND D BY C3+ IONS, Journal of physics. B, Atomic molecular and optical physics, 28(21), 1995, pp. 4607-4618
We have computed cross sections for charge transfer between C3+(1s(2)2
s S-2) and H(1s S-2) for relative collision energies in the range 0.00
4 less than or equal to E less than or equal to 90 eV amu(-1). The mol
ecular orbital data were taken from Errea et al (1991a); both triplet
and singlet spin symmetries were considered. In order to extend the ca
lculations to low energies, where the rate coefficient is required for
astrophysical applications, a quantal treatment of the molecular dyna
mics was adopted. Comparison is made with previous calculations and wi
th experiment, including the recent measurements of Havener et al (199
5). At low energies, cross sections for electron capture from deuteriu
m are found to be significantly smaller than the corresponding ones fo
r hydrogen owing to the dynamical effect of the greater reduced mass.
