Abstract

In this work we study the E1 decay processes, ³P₁ → ³S₁γ, and ³S₁ → ³P₁γ in the framework of Bethe-Salpeter equation and calculate their decay widths. We have used algebraic forms of Salpeter wave functions obtained through analytic solutions of mass spectral equations for ground and excited states of ³S₁, and ³P₁ equal mass quarkonia in approximate harmonic oscillator basis to do analytic calculations of their decay widths. These decay widths have been compared with data and other models.
