摘要：

Resonances recently discovered in πN phase-shift analyses are assigned to linear Regge trajectories. The proposed classification is interpreted as evidence for (i) secondary trajectories displaced down from the leading trajectories by αŜαL-n (n an integer) and (ii) approximate degeneracy of trajectories with opposite parity, the same signature, and equal isospin (i.e., MacDowell symmetric). © 1968 The American Physical Society.
