Description
We show that using the modified form of the Dirac Hamiltonian as suggested by Bekenstein does not affect the analysis of QSO data pertaining to a measurement of α variation. We obtain the present time limit on Bekenstein's parameter, tan2 χ=(0.2±0.7)x10-6, from the measurement of the hydrogen 2p fine structure using a value of α obtained from different experiments
