This dissertation describes the measurement of the top quark mass m_t using events recorded during a 125 pb^-1 exposure of the D0 detector to √s=1.8 TeV $$\bar{p}$$p collisions. Six events consistent with the hypothesis t$$\bar{t}$$ → bW⁺, $$\bar{b}$$W^-t based on these relative solution likelihoods gives m_t2+, $$\bar{b}$$W^- → b$$\bar{l}$$v, $$\bar{b}$$q$$\bar{q}$$ , and this, in combination with an estimate on the likelihood that each event is top, yields m_t = 173.3 ± 5.6 (stat.) ± 6.2 (syst.) GeV/c²t = 173.1 ± 5.2 (stat.) ± 5.7 (syst.) GeV/c²
