COMPLETE SPECTROSCOPY OF AN ISOBARIC ANALOG RESONANCE WITH THE (E,E'P) REACTION

It is demonstrated by the example of the E(x) = 16.28 MeV, J(pi); T = 1(-); 6 state in Zr-90 that a high-resolution Zr-90(e, e'p)Y-89 experi ment can provide a nearly model-independent full characterization of a ll relevant spectroscopic properties of an isobaric analog state. The proton angular correlation data and branching ratios determine the tot al and partial widths into radiative and particle decay channels. A ph enomenological wave function is deduced from the form factor.
