We present spectral weight mapping in the momentum space for La2-xSrxCuO4 using angle-resolved photoemission spectroscopy. The spectral weight of the nodal states, which shows suppression in previous results, is enhanced and shows sharp peaks in the second Brillouin zone for the overdoped sample due to matrix element effects, although they remain much weaker than the other cuprates.
