Abstract
Experimental results for the electronic Raman effect in differently do ped Cu-O superconductors are presented. Below T-c both critical pair b reaking at frequencies close to the maximum of the gap and thermal pai r 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 typ ical for an unconventional gap with line nodes.
