We have,measured,the mean,lifetime of the hadrons,containing,b quarks,that are produced,in e+e- annihilation,at fi,= 29 GeV. We use,the full sample,of data collected by the MAC detector at the SLAC storage ring, PEP, including those,recently,acquired,with,a precision,vertex,detector.,The,result,is rb = [1.29 f,0.20(stat.) f O.O7(syst.)ps)
