Deep excursion beyond the proton dripline. I. Argon and chlorine isotope chains

The proton-unbound argon and chlorine isotopes have been studied by measuring trajectories of their decay-in-flight products by using a tracking technique with micro-strip detectors. The proton (1p) and two-proton (2p) emission processes have been detected in the measured angular correlations “heavy...

description The proton-unbound argon and chlorine isotopes have been studied by measuring trajectories of their decay-in-flight products by using a tracking technique with micro-strip detectors. The proton (1p) and two-proton (2p) emission processes have been detected in the measured angular correlations “heavy-fragment”+p and “heavy-fragment”+p+p, respectively. The ground states of the previously unknown isotopes 30Cl and 28Cl have been observed for the first time, providing the 1p separation energies Sp of −0.48(2) and −1.60(8) MeV, respectively. The relevant systematics of 1p and 2p separation energies have been studied theoretically in the core+p and core+p+p cluster models. The first-time observed excited states of 31Ar allow to infer the 2p-separation energy S2p of 6(34) keV for its ground state. The first-time observed state in 29Ar with S2p = −5.50(18) MeV can be identified either as a ground or an excited state according to different systematics.
