Abstract
The effect of configuration crossover on excited 4f6(7FJ) levels has been investigated by electronic Raman scattering in Sm1-xYxSe and Sm1-xYxS. The multiplet levels are wiped out when they merge with the conduction band, or when interacting with phonons. Polarized Raman-scattering data on Sm1-xYxS for x>0.15 show that the contribution from J-multiplet levels is unobservable and that the peak near 250 cm-1 arises from optic phonons and not from J=0→J=1 excitations.
