In spite of these difficulties, it is interesting to see how Racah s most vulnerable formula, eq. (82), which determines the lowest levels of the doubly ionized lanthanides, has stood the test of time. For N = 1 we get, from that equation,... 

Tables 1.13a and 1.13b comprise the ground levels and ionization potentials of the neutral through triply ionized lanthanides (Martin et al., 1974).

Ground levels and ionization potentials for the neutral and singly ionized lanthanide atoms. The designation of the ground level of Tb 11 is enclosed in braces because the indicated level has not yet been experimentally established as lowest. , ...

Although in the dielectrics the mobilities of the carriers are too small and their effective masses too large for the formation of shallow donor and acceptor states, the initial Hamiltonian describing the system of the host and Ln"" is the same as that for donor and acceptor impurities in semiconductors. In there is a one-electron approximation after the IT, the system consists of an unperturbed crystal with periodic potential—ionized lanthanide ion —and a free electron (in the...
