Title: Mass determination near N = 20 for Al and Na isotopes

We report on the mass measurements of 31;32Na and 29;34;35Al, performed with the TITAN Penning trap mass spectrometer at TRIUMF. The mass excesses were found to be 12246(14) keV and 18638(37) keV for 31;32Na and -18207:77(37) keV, -3000:5(29) keV, and -223:7(73) keV for 29;34;35Al, respectively. Our measurements con rm the observation of a crossover in the two-neutron separation energies of 33Mg and 34Al. We did not observe the recently reported, long-lived, isomeric state of 34Al, but, based on the previously measured half-lives, the mass value of the ground state was determined.
