On the effective potentials in the nucleon

In order to obtain a good fit to {{F_2ⁿ } {/ {{F_2ⁿ } {F_2^p }}} ; . } {F_2^p }} we propose an effective potential model which the up and down quarks are confined with different strengths. We choose the harmonic oscillator, with equal components S+V because of analitical results in the Dirac equation we can obtain. The total momentum results very close to 1.
