Question:
Consider a three-dimensional ket space. If a certain set of ortho-normal kets?say, | 1 >, | 2 >, and | 1 > ? are used as the base kets, the operators A and B are represented by with a and b both real.
a. Obviously A exhibits a degenerate spectrum. Does B also exhibit a degenerate spectrum?
b. Show that A and B commute.
c. Find a new set of ortho-normal kets which are simultaneous eigenkets of both A and B. Specify the eigenvalues of A and B for each of the three eigenkets. Does your specification of eigenvalues completely characterize eacheigen ket?
