757. Problem 40.19P (HRW) The probability density for the region of a square well of width L, and , drops off exponentially according to
where C is a constant. (a) We have to show that the wave function is a solution of the one-dimensional form of the Schrödinger’s equation, and have to find the value of k for this to be true. |
Solution: Click For PDF Version The one-dimensional Schrödinger equation for a particle of mass m, energy E, moving in the square well potential , in the region will be If we have . Substituting in the Schrödinger equation given above, we get This implies that
