M. Rafi et Altuwirqi R",fayyazuddin, THE RYDBERG-KLEIN-REES POTENTIAL-ENERGY CURVE OF THE A 1-SIGMA(+) STATE OF KH, Journal of physics. B, Atomic molecular and optical physics, 29(14), 1996, pp. 533-536
New spectroscopic data have been used to extend the Rydberg-Klein-Rees
potential energy curve of the A (1) Sigma(+) state of the KH molecule
from upsilon = 27 to 38.
