Deep excursion beyond the proton dripline. I. Argon and chlorine isotope chains. Physical Review C, 98 (6), 1-13.2469-9985 (impreso)2469-9993 (electrónico)https://hdl.handle.net/11441/98401The 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.application/pdf13 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1103/PhysRevC.98.064308
