The nature of transmission coefficient |T(x)|² of X-ray evanescent wave, x (=θ/θ_c) being normalized angle, for grazing incidence around the total external reflection angle is discussed. Refractive index n of X-ray is expressed by n = 1 - δ -I · β . A new equation which explains exactly the peak position x_p of the function |T(x)|² is presented. The value of x_p² is given as a solution of a cubic equation\n 4g³ + 3γ g² + 6γ g + (4γ - 1)γ = 0, with γ = (β/δ)² and g = 1 - x_p² . According to the equation, with increasing values of beta/δ, the peak position x_p shifts to lower angle at first and increase again quickly. The peak heights |T(x_p)|² are also calculated. The nature of the cubic equation is investigated in details. The shapes of |T(x)|²$ are compared with the experimental values of an exit angle dependence of X-ray emission which are measured during RHEED observation.
