gnuplot / spherical_harmonics / index (E) Spherical Harmonics Parametric Spherical harmonics Various quantum numbers Deformed nucleus [ver.4] Spherical Harmonics To show an example of 3-dim functional plot, here we present the well-known Spherical Harmonics. The function in the polar coordinate is expressed by parameters, and the function for some l and m values are displayed. Parametric expression Spherical harmonics Various angular momenta and magnetic quantum numbers l=1,m=-1,+1 l=2,m=-2,-1,0,+1,+2 l=3,m=-3,…,+3 Deformed Nucleus (Legendre Expansion) [ver.4]
