Abstract

Experimental results for the electronic Raman effect in differently doped Cu−O superconductors are presented. Below Tc both critical pair breaking at frequencies close to the maximum of the gap and thermal pair breaking in the limit of small energy transfer is observed and found to be strongly polarization dependent. For all doping levels studied the spectra exhibit frequency and temperature power laws which are typical for an unconventional gap with line nodes.
