We use a large-scale [Formula Presented] calculation for [Formula Presented]Li with microscopically derived two-body interaction to construct the [Formula Presented] shell effective Hamiltonian, electric quadrupole, and magnetic dipole operators. While the E2 and M1 [Formula Presented] operators are one-body operators with free nucleon charges, the effective operators are two-body operators with substantially different renormalization for the isoscalar and isovector matrix elements, especially for the E2 operator. We show that these operators can be very well approximated by one-body operators provided that effective proton and neutron charges are used. The obtained effective charges are compatible with those used in phenomenological shell-model studies. The two-body part of the effective operators is estimated. \textcopyright 1997 The American Physical Society.
