Odd and even partial waves of f \u3b7\u3c0 12\u3b7\u3c0 12 and \u3b7\u2032\u3c0 12\u3b7\u2032\u3c0 12 in \u3c0 12p\u2192\u3b7(\u2032)\u3c0 12p\u3c0 12p\u2192\u3b7(\u2032)\u3c0 12p at 191 GeV/c
Exclusive production of \u3b7\u3c0 12 and \u3b7 \u3c0 12 has been studied with a 191 GeV/c \u3c0 12 beam impinging
on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal different odd/even angular
momentum (L) characteristics in the inspected invariant mass range up to 3 GeV/c2. A striking similarity
between the two systems is observed for the L = 2, 4, 6 intensities (scaled by kinematical factors) and the
relative phases. The known resonances a2(1320) and a4(2040) are in line with this similarity. In contrast,
a strong enhancement of \u3b7 \u3c0 12 over \u3b7\u3c0 12 is found for the L = 1, 3, 5 waves, which carry non-q\uafq quantum
numbers. The L = 1 intensity peaks at 1.7 GeV/c2 in \u3b7 \u3c0 12 and at 1.4 GeV/c2 in \u3b7\u3c0 12, the corresponding
phase motions with respect to L =2 are different
