The state of an electron in a hydrogenic atom is given by the un-normalised wavefunction Φ = {Y10(θ, φ) + 1√2 Y11(θ, φ)}R(r), where Ylm(θ, φ) are spherical harmonics and R(r) is the radial function. The probability that a measurement of Lz will give an eigenvalue of ℏ (which corresponds to m = 1) is:
