Abstract: We study the properties of axial vector mesons a1 and b1 as relativisticS-wave states which are predicted in the U~12-scheme, through the analyses oftheir radiative and pionic decays. Specifically, partial widths of the stronga1 b1 -> rhoomega pi processes, their D-S-wave amplitude ratios, andradiative transition widths of a1b1 -> pi gamma processes are calculated byusing a simple decay interaction model, and made a comparison with therespective experimental values.
