Precision mass measurements of 44V and 44mV for nucleon-nucleon interaction studies

We discuss the motivation and technique of Penning trap mass spectrometry applied to radioactive 44V and 44mV, using the LEBIT 9.4 T Penning trap mass spectrometer at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University. A complementary measurement of these nuclides, performed at the CSRe in Lanzhou, China, was recently published, but with errors several times larger than obtainable for a short-lived radionuclide in a Penning trap. Interpretation of the higher precision results is ongoing and a full accounting of this measurement is anticipated in the coming months.
