Abstract
A high-statistics photon spectrum from the reaction , measured with a 0.72-meV-resolution pair spectrometer is compared with different theoretical spectra folded with the measured photon line from the reaction . A value of fm (theoretical error included) is deduced assuming a fixed value of fm. The problem of extracting using the present theories is indicated.
