Then, We give its solution. We demonstrate that the $QSHJES_{1\over2}$ have two explicit forms, which represent the two possible projection of the Spin 1/2.Latex, 8 pages, no figureQuantum PhysicsHigh Energy Physics - TheoryThe Relativistic Quantum Stationary Hamilton Jacobi Equation for Particle with Spin 1/2text
