The potential energy barrier of the 2(1)Pi state in KLi.
The polarisation labelling spectroscopy technique has provided detailed information about the shape of the potential barrier to dissociation of the 2(1)Pi state in KLi. The potential curve of the 2(1)Pi state is constructed using the Inverted Perturbation Approach method. Our analysis shows that the barrier height is DeltaE=20.8+/-1.0 cm(-1) relative to the dissociation limit and the barrier maximum is located at Rbar=8.2+/-0.1 A.
