Abstract

The weak electric form factor

g_{2}

is calculated in the nonrelativistic quark model (NRQM) and the MIT bag model for weak

Δ S = 1

semileptonic transitions. The bag-model result is

\frac{g_{2}}{g_{1}} = 0.30

with the NRQM result roughly twice this. Other weak transition form factors are tabulated, including expected SU(3)-breaking effects.
