A new interaction called PSDPFB has been derived in the full p-sd-pf model space allowing one jump with a 4He core to describe the 1 \hbar \omega intruder states in sd shell nuclei. This new interaction was tested by calculating the evolution of the negative parity states throughout the shell. A low-lying 0- state in 40Ca is predicted. The interaction was applied to obtain the N=18 and 20 isotones spectra. Results for the isotones 32Si, 34S and 36Ar and those for 34Si, 36S and 38Ar are presented and compared to experiment
