Unformatted text preview: 3. Given an attractive central potential of the form V =V exp(r/a ), solve the Schr¨odinger equation for the sstates by making the substitution ξ = exp[r/ (2 a )]. Obtain an equation for the eigenvalues. 4. Shankar, problem 12.6.11, parts (1) and (2) only. By “parity” is meant the following: Each solution will satisfy ψ (x ) = ± ψ ( x ), where the + sign means that the state has even parity, and thesign means that the state has odd parity. In spherical coordinates, if we write x = r, θ, φ , thenx = r, πθ, π + φ . 1...
