Abstract

We calculate the spectrum and wave functions (WFs) of various states of bottomonium mesons ($b\overline{b}$) using a non-relativistic quark potential model (NRQPM). The calculated WFs are used to compute the radiative widths of various states of $b\overline{b}$. The strong decays widths of bottomonium states are also calculated using $^3P_0$ model by choosing simple harmonic oscillator wave functions (SHOWFs). The $\beta$ of SHOWFs for various states of the mesons are measured by fitting the numerical wave functions. The radiative and strong decay widths are used to calculate the branching ratios of $b\overline{b}$ mesons. We also compare our calculated masses and widths with available experimental data.
