Phase ambiguity of the threshold amplitude in pp -> pp\pi^0


Measurements of spin observables in pp -> {\vec p}{\vec p}\pi^0 are suggested to remove the phase ambiguity of the threshold amplitude. The suggested measurements complement the IUCF data on {\vec p}{\vec p} -> pp\pi^0 to completely determine all the twelve partial wave amplitudes, taken into consideration by Mayer [15] and Deepak, Haidenbauer and Hanhart [20].Comment: 4 pages, 1 table
