【 摘 要 】

The mass spectrum of $car{b}$ meson is investigated with an effective quark-antiquark potential of the form $dfrac{-𝛼_{c}}{r} + Ar^{𝜈}$ with 𝜈 varying from 0.5 to 2.0. The 𝑆 and 𝑃-wave masses, pseudoscalar decay constant, weak decay partial widths in spectator model and the lifetime of 𝐵c meson are computed. The properties calculated here are found to be in good agreement with other theoretical and experimental values at potential index, 𝜈 = 1.
