1. In class we "derived" the electron-nucleus hyperfine interaction. Evaluate the expectation value of this interaction for two different cases for an electron in an eigenstate of hydrogen atom with quantum numbers nlmm_s with n=2, l=0, m=0, m_s=1/2 and with n=2, l=1, m=0, m_s=1/2. In both cases assume that the proton spin is m^p_s=1/2
