We present the first data on the systematics of the resonant M-4,M-5-scattering (3d(9)4f(n+1) excitation; n ground state occupation) from rare earths with a final state 4p hole. We give evidence for the final state interaction of the 4f(n+1)4p(5) configuration with the configurations (4d(8)4f(n+2)) and (4d(8)4f(n+1)epsilon; epsilon means continuum). The interaction is stronger at the MS threshold. Data on La, Ce7Rh3, CeRh2 and Gd are given.

Abstract
We present the first data on the systematics of the resonant M-4,M-5-scattering (3d(9)4f(n+1) excitation; n ground state occupation) from rare earths with a final state 4p hole. We give evidence for the final state interaction of the 4f(n+1)4p(5) configuration with the configurations (4d(8)4f(n+2)) and (4d(8)4f(n+1)epsilon; epsilon means continuum). The interaction is stronger at the MS threshold. Data on La, Ce7Rh3, CeRh2 and Gd are given.File in questo prodotto:
