Using Angle Resolved Photoemission ARPES , we present the first observation of sharp quasiparticle like peaks in a CMR manganite. We focus on the pi,0 regions of k space and study their electronic scattering rates and dispersion kinks, uncovering the critical energy scales, momentum scales, and strengths of the interactions that renormalize the electrons. To identify these bosons we measured phonon dispersions in the energy range of the kink by inelastic neutron scattering INS , finding a good match in both energy and momentum to the oxygen bond stretching phonon
