What it covers
CERN INTC addendum asking whether N=32 is a real magic number, to be tested with high-precision masses rather than only with spectroscopy.
Methods and setup
ISOLTRAP masses of calcium, scandium, or neighbouring chains around N=32, using MR-ToF and the Penning trap.
Why it matters
N=32 appears closed in some calcium and argon isotopes and not in others. A mass kink is the ground-state verdict on that claimed magic number.
