Abstract
--------
This thesis presents the results from the investigation of time dependent
B0d-B0dbar  mixing in B --> lepton  X, B0d --> D*-  X, D*- -->D0bar pi-, 
D0bar --> K+ pi- channel in ppbar collisions at sqrt{s}=1.8 TeV using 110 pb-1
data collected with the CDF detector at the Fermilab Tevatron Collider. The D0
vertex is reconstructed. The B0 decay length is estimated using the distance
from the primary vertex to the measured position of the D0 vertex. The B0
momentum is estimated using the D0 momentum and a kinematic correction factor
from Monte Carlo. With the dilution floating, Delta Md = 0.55 + 0.15 - 0.16
(stat) +/- 0.06(syst) ps-1 is measured.
