${{\mathit \Delta}{(1232)}}$ MAGNETIC MOMENTS

${{\mathit \Delta}{(1232)}^{++}}$ MAGNETIC MOMENT

INSPIRE search
The values are extracted from UCLA and SIN data on ${{\mathit \pi}^{+}}{{\mathit p}}$ bremsstrahlung using a variety of different theoretical approximations and methods. Our estimate is $\mathit only$ a rough guess of the range we expect the moment to lie within.
