We apply the dispersive optical model (DOM) wave functions to the traditional (,) analysis and investigate the consistency of the DOM spectroscopic factor that describes the (,) cross section with the result of the (,) analysis. DOM + distorted wave impulse approximation analysis on Ca(,)K data generates a proton spectroscopic factor of 0.560, which is meaningfully smaller than the DOM value of 0.71 shown to be consistent with the (,) analysis. The inconsistency in the spectroscopic factor suggests there is urgent need for improving the description of - scattering in a nucleus.
