Abstract
The reaction pp --> p(f)(eta pi(+)pi(-))p(s) has been studied at 450 GeV/c. There is clear evidence for an a(2)(1320)pi decay mode of the eta(2)(1645) and eta(2)(1870). In addition, there is evidence for an a(0)(980)pi decay mode of both resonances and an f(2)(1270)eta decay mode of the eta(2)(1870) . No evidence is found for a J(PC) = 2(++)a(2)(1320)pi wave.
