A particle of mass m and kinetic energy E > 0 approaches an attractive delta-function well located at x = 0 V (x) = -Voa 8(x) where Vo, a are positive contants and Vo has units of energy and a has units of length. (a) Find expressions for the reflection and transmission probabilities. (b) Set [(ma²)Vo/(2h²)] = 1 and plot the reflection coefficient as a function of dimensionless parameter x = E/Vo, (0 < x<00).
