High-precision Penning trap mass measurements of neutron-rich sulfur isotopes at the N=28 shell closure Academic Article uri icon


  • Direct mass measurements of the neutron-rich S40-44 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(S40)=-22 837.8(3.9) keV, ME(S41)=-19 008.6(4.1) keV, ME(S42)=-17 637.9(2.7) keV, ME(S43)=-12 195.5(4.9) keV, and ME(S44)=-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. 2009 The American Physical Society.
