The spectrum and production mechanism of baryoniums with a pair of junction and antijunction lines are studied by dual topological unitarization as the basis, It is suggested that there are three parallel M_4 trajectories with the same topology and the spacing among them is about 0.5, reflecting the difference of the intercepts between input unnatural and natural parity baryon trajectories. A possible interpretation is given on narrow NN^^- widths of some empirical peaks, by introducing the properties of a qq-system on the spin and space symmetry. It is also shown that the forward production of M_4 baryoniums in conventional meson-baryon scattering is dominated by the exchange of M_0 and M_2 baryoniums. An attempt is made at spin-parity assignments of some empirical peaks.
