(a) The photon energy hν versus r2 for transition 27. The solid line is the linear least square fitting. The intercept 11316.22 cm−1 is the binding energy of transition 27. (b) The binding energy of transition Ce(3H4)← Ce−(4 H7/2) as a function of the kinetic energy of photoelectrons. The dashed lines indicate the uncertainty ± 0.21 cm−1.
