Description

The narrow structures have been observed at the kinetic energies TL= 605 and 680 MeV (√s= 2.16, 2.19 GeV) in the energy dependence of the p-p elastic analyzing power measured in KEK. We propose a method for determining the spin-parity of a possible di-proton resonance, which is assumed to cause the narrow structure of the Ay-data. The results of the analysis of this data and the dσ / dΩ (90deg)-data from Saclay indicate that the assignment of 3P2, 3F3 or 3H5-resonance is plausible for the first structure (√s= 2.16 GeV), while in the 3P2 case the fit to Saclay data is worse than that in the 3F3 or 3H5 case.
