Abstract

Prospects of experimental studies of argon and chlorine isotopes located far beyond the proton dripline are studied by using systematics and cluster models. The deviations from the widespread systematics observed in ${}^{28, 29}{Cl}$ and ${}^{29, 30}{Ar}$ have been theoretically substantiated, and analogous deviations have been predicted for the lighter chlorine and argon isotopes. The limits of nuclear structure existence are predicted for Ar and Cl isotopic chains, with ${}^{26}{Ar}$ and ${}^{25}{Cl}$ found to be the lightest sufficiently long-living nuclear systems. By simultaneous measurements of protons and $γ$ rays following decays of such systems as well as their $β$ -delayed emission, an interesting synergy effect may be achieved, which is demonstrated by the example of ${}^{30}{Cl}$ and ${}^{31}{Ar}$ ground-state studies. Such a synergy effect may be provided by the new EXPERT setup (EXotic Particle Emission and Radioactivity by Tracking) being operated inside the fragment separator and spectrometer facility at GSI, Darmstadt.
