The data are from this work (solid square), from ref. 74, and from Atomic Mass Evaluation AME202043. The Sp > 0 data points are fitted with a liquid-drop model based function, which is then extrapolated to proton-unbound nuclei. Isotopes with proposed (This work,8,34,35) dominant s1/2 proton component in the wave function of the ground state are indicated. All uncertainties are one standard deviation.
