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

Here, we discuss the motivation and technique of Penning trap mass spectrometry applied to radioactive 44 V and 44m V, 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.
