Abstract
The induced pseudotensor constant (weak electricity) of the nucleon is calculated in the framework of the chiral quark-soliton model. This q uantity originates from G-parity violation and, hence, is proportional to m(u) - m(d). We obtain for m(u) - m(d) = - 5 MeV a value of g(T)/g (A) = - 0.0038.
