We discuss the use of the no-core Pauli operator for calculating the effective shell-model interaction. The goal is to obtain a simple, but useful, form of the effective interaction for reproducing low-lying states, thereby reducing the effect of intruder states on these low-lying configurations. The techniques are applied to 4He as a test case. The method seems to converge well with increasing no-core space size.
