Explicit Wave Functions for Any Spin

A general method is given for calculating the exact form of the helicity eigenstates of a wave function for any spin. Explicit expressions of the wave functions for spin $S=1, \frac{3}{2}, 2, \mathrm{and} \frac{5}{2}$ are listed. Examples of helicity amplitudes for the production of $S={\frac{3}{2}}^{+}$ and $S={\frac{5}{2}}^{+}$ isobars in proton-proton scattering are computed.
