We report e(+)e(-) -> b (b) over bar cross section measurements by the BABAR experiment performed during an energy scan in the range of 10.54 to 11.20 GeV at the SLAC PEP-II e(+)e(-) collider. A total relative error of about 5% is reached in more than 300 center-of-mass energy steps, separated by about 5 MeV. These measurements can be used to derive precise information on the parameters of the Y(10860) and Y (11020) resonances. In particular we show that their widths may be smaller than previously measured.
