We present details of carrier properties in high quality ${\rmBa(Fe_{1-x}Co_{x})_2As_2}$ single crystals obtained from electronic Ramanscattering. The experiments indicate a strong band and momentum anisotropy ofthe electron dynamics above and below the superconducting transitionhighlighting the importance of complex band-dependent interactions. Thepresence of low energy spectral weight deep in the superconducting statesuggests a gap with accidental nodes which may be lifted by doping and/orimpurity scattering. When combined with other measurements, our observation ofband and momentum dependent carrier dynamics indicate that the iron arsenidesmay have several competing superconducting ground states.
