RT Journal Article T1 Deep excursion beyond the proton dripline. I. Argon and chlorine isotope chains A1 Mukha, I. A1 Grigorenko, L. A1 Kostyleva, D. A1 Dueñas Díaz, José Antonio AB The proton-unbound argon and chlorine isotopes have been studied by measuring trajectoriesof their decay-in-flight products by using a tracking technique with micro-strip detectors. Theproton (1p) and two-proton (2p) emission processes have been detected in the measured angularcorrelations “heavy-fragment”+p and “heavy-fragment”+p+p, respectively. The ground states ofthe previously unknown isotopes 30Cl and 28Cl have been observed for the first time, providing the1p separation energies Sp of −0.48(2) and −1.60(8) MeV, respectively. The relevant systematics of1p and 2p separation energies have been studied theoretically in the core+p and core+p+p clustermodels. The first-time observed excited states of 31Ar allow to infer the 2p-separation energy S2pof 6(34) keV for its ground state. The first-time observed state in 29Ar with S2p = −5.50(18) MeVcan be identified either as a ground or an excited state according to different systematics.
