Zusammenfassung:The Fermi motion parameter \(p_{_F}\) is the most important parameter of ACCMM model, and the value \(p_{_F} \sim 0.3\) GeV has been used without clear theoretical or experimental evidence. So, we attempted to extract the possible value for \(p_{_F}\) theoretically in the relativistic quark model using quantum mechanical variational method. We obtained \(p_{_F} \sim 0.5\) GeV, which is somewhat larger than 0.3, and we also derived the eigenvalue of \(E_B \simeq 5.5\) GeV, which is is reasonable agreement with \(m_B=5.28\) GeV.
