We can start with these initial values of and to obtain more accurate
values by least square fitting (discussed in Chapter 2) to the ten non-zero
values in Table 3-1. The sum of squares of the differences between theory
and experiment, in this case, can be denoted as First, is fixed at
0.17, and a is varied to calculate the value of S, as shown in Table 3-2.

Finally, by least square fitting, we get:
