The widths of all basic decay modes of these mesons are estimated. The value of the Qsub(A)-Qsub(B) mixing angle phi=34 deg is obtained. The deviation of the singlet-octet states mixing angle for H(1190) and H'(1480) mesons from its ideal value equals 12 deg. The radiative decay widths of the B(1235), H(1190), Q sub 1 (1280), and Q sub 2 (1400) mesons are obtained. (Atomindex citation 16:056267) 收起
