Abstract
We have studied the temperature dependence of crystal field (CF) excitation linewidths of lanthanide ions (Er and Ho) in YBa(2)Cu(3)0(7) by neutron scattering. The Ho data reveal an anomaly in the CF damping around T-c with no evidence of a coherence peak below T-c. We have applied the theory of Becker, Fulde and Keller to derive the reduced s-f coupling constants from the CF linewidth data for the ions Er, Ho and Tm.
