Consider an electron in a hydrogen atom with -1. there are three possible eigen- states of the operator l2, given by |l, m) 11, 1), |1,0), and |1,-1). (a) recall that the raising/lower operators are given by ll ily. also recall the rela- tionship use this relationship to determine the 3x3 matrix representation of ly (using a basis com- prised of eigenstates of lz). (b) what are the eigenvalues and associated eigenstates of the operator ly? (c) if the quantum state is initially |1,1), what is the probability that a measurement of l yields 0?
