Spin wave excitations and the electron self-energy corrections in the ferromagnetic phase of iron are studied using the Naval Research Laboratory tight-binding model. It is found that the spin wave excitation spectrum obtained with this model is in good agreement with the experimental results. Transverse spin fluctuations contribute to the self-energy and reduce the band width uniformly, but does not cause a prominent kink structure in the quasiparticle dispersion near the fermi level. Comparison with recent angle-resolved photoemission experiments on Fe is made.
