Findings
Resonance at 1.5 MeV confirmed by phase shift shape
The phase shift matches the 15N level characteristics
Potential model adequately describes the scattering phase shift
Abstract
The phase shift analysis for determination of the 2S1/2 resonance at 1.5 MeV was carried out on the basis of the known experimental measurements of the excitation functions of the p14C elastic scattering at four angles from 90 to 165 grad. and more than 100 energy values in the range from 600-800 to 2200-2400 keV. The obtained shape of the resonance 2S1/2 phase shift coincides with the characteristics of the corresponding level of 15N in whole, and the suggested potential acceptably describe this scattering phase shift.
