Abstract
Single-crystalline Nd1.84Ce0.16CuO4 with a superconducting transition temperature of 19.3 K has been studied above and below Tc using polarized Raman scattering. Electronic, crystal-field, and vibrational excitations have been detected. In the superconducting state, the formation of an almost isotropic gap 2Δ is observed which varies between 4.1 and 4.9 in units of kTc. This indicates that Nd1.84Ce0.16CuO4 is different from the other cuprate systems.
