摘要：
The general nodal structure approach is applied to the recent gamma (p) over right arrow --> eta p T-asymmetry data from ELSA. The reaction mechanism is found to require, in addition to the dominant S-11 and D-13 resonances, contributions from P-13 and D-15 resonances. This finding is confirmed within a simple dynamical approach. An indication on the presence ofa predicted P-13 nucleonic resonance is observed.
