A New Method for Obtaining the Baryons Mass under the Killingbeck Plus Isotonic Oscillator Potentials

Table 5

Mass spectrum of some of 1 and 2 star baryons resonances (in MeV) up to 2.1 GeV calculated with the mass formula (22). column contains our calculations with the parameters of Table 2 and column 6 indicates the percentage of relative error for our calculations.
