Potential curves for the 4p A Π and 4p B ²Σ states of the K–He molecule for ab initio potentials of Nakayama & Yamashita (2001) (dashed green line) are compared to potentials of Santra & Kirby (2005) (dotted red line), pseudo-potentials of Pascale (1983) for the B ²Σ state (dashed blue line), and the adopted potentials (black line).
