Exercise 10.14 A particle is initially in its ground state in an infinite one-dimensional potential box with sides at x = 0 and x a. If the wall of the box at x-a is suddenly moved to x = 10a, calculate the probability of finding the particle in (a) the fourth excited (n = 5) state of the new box and (b) the ninth (n 10) excited state of the new box.
Example To obtain the ground state energy of a particle in a one-dimensional box, a graduate student used a postulated wavefunction of the form Y = e-ax? where a is a variational parameter. Along the process, the student obtained the following result. ſy trial ÀY trial Etrial = There are trial trial Complete the variation calculation procedure and obtain the optimal value of a.
