摘要：
The use of Wronskians with properly chosen linearly independent solutions of the Schroumldinger equation greatly facilitates the calculation of the transmission probability for scattering in one dimension and also provides a reliable test for the accuracy of the calculation. We apply the approach to a Gaussian barrier and a Gaussian well, and test its accuracy for an exactly solvable model. (C) 2011 American Association of Physics Teachers. [DOI: 10.1119/1.3596393]
