Radiative pi$^{+}$p scattering and the magnetic moment of the DELTA$^{++}$
The size of the peak expected in pion-proton bremsstrahlung in the region of the Delta /sup ++/ resonance is calculated using an unambiguous low-energy theorem.

| Sumario: | The size of the peak expected in pion-proton bremsstrahlung in the region of the Delta /sup ++/ resonance is calculated using an unambiguous low-energy theorem. The only unknown parameter is the magnetic moment of the resonance. From the absence of any resonant structure in the data one obtains for it mu /sub delta /=3.7+or-1.4 in units 2eh(cross)/2M/sub Delta /c. This is in excellent agreement with the SU(6) prediction mu /sub Delta /=3.66. (16 refs). |
