Publisher's Note: Two-proton decay of12O and its isobaric analog state in12N [Phys. Rev. C86, 011304(R) (2012)]

Proton-decaying states in light nuclei and the first observation of Na17

“…The 8 B IAS was the first case for this decay mode where all of the decay products were measured (two protons, the 6 Li core and the γ). Another possible case was observed in the 2p + 10 B decay channel corresponding to a state in 12 N [27]. If the 10 B nucleus were formed in its ground state, then the measured excitation energy of this peak would not correspond to any known state in either 12 N or its mirror 12 B.…”

Two-proton decay from the isobaric analog state inB8

“…With increasing mass, 12 O is the next known 2p emitter after 8 C. Its isobaric analog state in 12 N has also been ascribed to this new third class of 2p emitters [4] decaying to the isobaric analog state in 10 B. In both 8 B IAS and 12 N IAS decay, the daughter isobaric analog states decay by γ emission, but in both studies [1,4] the γ ray was not detected allowing a small uncertainty to our interpretation of the decay sequence and thus in the existence * Present Address: Department of Physics, University of Connecticut, Storrs, Connecticut 06269, USA of this third class of 2p decay.…”

This deficiency is remedied in the present work where the 2p decay of 8 B IAS is revisited and the γ ray from the decay of the 6 Li IAS daughter is observed.…”

Precision mass measurements of short-lived nuclides for nuclear structure studies at TITAN

“…TITAN mass measurements of 9−11 Be removed atomic mass uncertainties as significant sources of error in determining the relative nuclear charge radius from the isotope shift [20]. The mass measurement of 12 Be [21] performed at TITAN contributed to the charge radius determination of 12 Be [38], and to a test of isobaric multiplet mass equation (IMME) [39].…”
