Notes: Predicted energies are calculated using \( E_{n,J} = E_n + [J(J+1) - \frac{3}{4}] \times 98 \) MeV, where \( E_n = -3390 + 1546n - 116n^2 \) MeV for \( J = \frac{1}{2} \). The total energy includes the proton rest mass (938 MeV) at the ground state (\( n = 4, J = \frac{1}{2} \)). Match quality reflects proximity to measured masses and consistency with quantum numbers (J, parity, etc.). For \( n > 7 \), the quadratic formula predicts decreasing energies (e.g., \( n = 8, E_n = 1554 \) MeV), which may not be physical, so the table is limited to \( n = 4 \) to \( n = 7 \).
