Homework Solutions # 3 (Liboff Chapter 5) 5.2 (a) If we interpret to be a probability amplitude for each neutron, R dx | | 2 = 1. We get A 2 Z a dx ( x- a ) 2 x 2 = A 2 " x 5 5- ax 4 2 + a 2 x 3 3 # a = A 2 a 5 30 = 1 So A = q 30 /a 5 . If we interpret | | 2 to be the neutron density, we should multiply A by 1000. Lets stick with the first. (b) Since is symmetric about x = a/ 2, half the neutrons must be between 0 and a/ 2. 500.
