Precision solution of the Schrödinger equation with Coulomb and linear confining potentials in momentum space

The eigenvalue of the confined potential

“…Furthermore, The Cornell potential (Coulombplus-linear potential) is very success in describing the spectrum of the quarkonium [1][2][3][4]. The eigenvalue of Cornell potential was studied for many years [5][6][7][8][9][10][11][12][13][14][15][16][17], and yet there is no exact result for the eigenvalues. References [5,12,[16][17][18] gave some approach formulas.…”

“…The eigenvalue of Cornell potential was studied for many years [5][6][7][8][9][10][11][12][13][14][15][16][17], and yet there is no exact result for the eigenvalues. References [5,12,[16][17][18] gave some approach formulas. In this paper, we obtain an exact formula for eigenvalue of the linear part of Cornell potential which can describe the high excited states for the quarkonium [19,20].…”
