Id. Williams et al., EXPERIMENTAL-OBSERVATION OF SUPERELASTIC SCATTERING OF ELECTRONS FROMA POSITIVE-ION, Journal of physics. B, Atomic molecular and optical physics, 28(17), 1995, pp. 555-558
The superelastic scattering of electrons from a positive ion has been
experimentally observed for the first time. A cross section of 12.0 x
10(-17) cm(2) was determined for the collisional quenching of the 1s(2
)2s2p(2) P-4 state of C+ at an energy of 3.5 eV. The principle of deta
iled balancing is used to compare with an R-matrix calculation for the
excitation collision strength to this state.
