[UPSC CSE 2007] Schrodinger’s Wave equation and applications (Q210, 20M)

A one-dimensional potential barrier is represented by the function V(x) = 0 \quad \text{for } x < 0 = V_0 \quad \text{for } x > 0 Where V_0 is positive. Find the transmission coefficient for particles of mass m incident from the left on the barrier.
