DOI: 10.1103/PhysRevA.72.0121041050-2947http://hdl.handle.net/10919/24778The energy spectrum of the Coulomb potential with minimal length commutation relations [X-i, P-j] = ih{delta ij(1 + beta P-2) + beta PiPj} is determined both numerically and perturbatively for arbitrary values of beta'/beta and angular momenta l. The constraint on the minimal length scale from precision hydrogen spectroscopy data is of the order of a few GeV-1, weaker than previously claimed.en-USIn Copyrightuncertainty relationlamb shiftfrequencyArticle - Refereedhttp://link.aps.org/doi/10.1103/PhysRevA.72.012104https://doi.org/10.1103/PhysRevA.72.012104
