Abstract
A study was made of the WO spin-density matrix elements in the o
reaction TI p~ n. The data were collected using a combination of scintillation counters and optical spark chambers designed to detect events of the type
+ TI
p-TI TI yyn. Incident pions of momenta 3.65, 4.5, and 5.5 GeV/c were produced by an internal target at the Argonne National Laboratory Zero Gradient Synchrotron. The values obtained for the WO spin-density matrix elements are inconsistent with the predictions of a simple model which allows for Reggeized p(765) and B(1235) exchange.
