Ground-state mass of ^{22}Al and test of state-of-the-art ab initio calculations

The ground-state mass excess of the T_{z}=-2 drip-line nucleus ^{22}Al is measured for the first time to be 18103(10) keV using the newly-developed B\rho-defined isochronous mass spectrometry method at the cooler storage ring in Lanzhou. The new mass excess value allowed us to determine the excitation energies of the two... Show more
