The branching ratio of the decay Br (t &rarr; c&gamma;) is calculated as function of the mixing parameters and masses of the neutral scalar fields. We obtain a Br (t &rarr; c&gamma;) of the order of 10&minus;8 for the considered regions of the mixing parameters. Finally, one upper bound for the possible events is estimated to be n=18 by assuming an expected luminosity of the order of 300 fb&minus;1. %K Two Higgs Doublet Models %K Rare Top Decays %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=76394
