please answer only part B! thanks 7) (14 points) An electron is in by the spherical harmonic Yeine), with (-2 and 2 a state in which the angular portion of the wavefunction is described a.) How many angular nodes does this function possess? b.) Give the values of the following integrals. Note: you should not have to carry out any integrations; just give the results. You should be able to evaluate most of them by inspection. si2 (o.p)Y (B.0) [email protected] de dp - 2π π f Srile.4%2(θ4)[email protected] - JJ (e.9) rale.9) [email protected]@ - 7) (14 points) An electron is in by the spherical harmonic Yeine), with (-2 and 2 a state in which the angular portion of the wavefunction is described a.)
