We have studied the effect of non-integer Orbital Angular Momentum (OAM) on OAM enhanced beam shifts, for in-plane (Goos-Hanchen) and out-of-plane (Imbert-Fedorov) shifts, using Hermite-Laguerre-Gaussian beams. Contrary to naive expectation we find, theoretically and experimentally, that the noninteger OAM beam shifts do not interpolate linearly between the integer OAM beam shifts.
