MONTE-CARLO TYPE RADIATIVE CORRECTION CALCULATIONS FOR LAMBDA-]PE(NU)OVER-BAR DECAY

Order-ct radiative corrections to one-dimensional distributions in Lam bda -->, pe $$($) over bar v decay are calculated. It is pointed out t hat the g(1)/f(1) determinations of the high statistics Lambda -->, pe $$($) over bar v experiments of the eighties contain systematic error s because of using wrong radiative corrections. These theoretical erro rs are about twice as large as the measurement error of the latest exp eriment, and could essentially effect the tests of the Cabibbo model o r the quark model calculations.
