Abstract
Using data collected by the CLEO II detector at a center-of-mass energ y on or near the Y(4S) resonance; we have determined the 90% confidenc e level upper limit B((B) over bar --> #Lambda(c)(+) e(-)X)/B((B) over bar-->(Lambda(c)(+) or <(Lambda)over bar>(-)(c))X)<0.05 for electrons with momentum above 0.6 GeV/c. We have also obtained the limit B(B- - -> Lambda(c)(+) (p) over bar e(-) (v) over bar(e))/B((B) over bar --> Lambda(c)(+) (p) over bar X) <0.04 at the 90% confidence level and mea sured the ratio B((B) over bar-->Lambda(c)(+)(p) over bar X)/B((B) ove r bar-->(Lambda(c)(+) or <(Lambda)over bar>(-)(c))X) = 0.57 +/- 0.05 /- 0.05.
