Direct mass measurements of the neutron-rich {sup 40-44}S isotopes were performed at the Low Energy Beam and Ion Trap facility at the National Superconducting Cyclotron Laboratory. The resulting mass excesses (MEs) are ME({sup 40}S)=-22 837.8(3.9) keV, ME({sup 41}S)=-19 008.6(4.1) keV, ME({sup 42}S)=-17 637.9(2.7) keV, ME({sup 43}S)=-12 195.5(4.9) keV, and ME({sup 44}S)=-9 204.2(5.2) keV, and they represent improvements by factors of 20 to 50 in the precision of previous mass measurements of these isotopes.
