We find that the kink's location transitions smoothly from a maximum binding energy of about 65 meV at the node of the d-wave superconducting gap to 55 meV roughly one-third of the way to the antinode. Meanwhile, the self-energy spectrum corresponding to the kink dramatically sharpens and intensifies beyond a critical point in momentum space. We discuss the possible bosonic spectrum ","authors_text":"D. S. Dessau, H. Eisaki, H. Iwasawa, H. Namatame, K. Shimada, M. Arita, M. Taniguchi, N. C. Plumb, T. J. Reber, Y. Aiura, Y. Cao, Y.
