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,...

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...

Several states of proton-unbound isotopes 30 Ar and 29 Cl were investigated by measuring their in-flight decay products, 28 S + proton + proton and 28 S + proton, respectively. A refined analysis of 28 S -proton angular correlations indicates that the ground state of 30 Ar is located at 2 . 45 + 0.05 − 0.10 MeV above the two-proton...

The NUMEN project aims at accessing experimentally driven information on Nuclear Matrix Elements (NME) involved in the half-life of the neutrinoless double beta decay (0νββ), by high-accuracy measurements of the cross sections of Heavy Ion (HI) induced Double Charge Exchange (DCE) reactions. Particular attention is given to the (18O,18Ne) and...

We describe the use of the 4 CHIMERA charged particle detector as a large efficiency -ray detector. The CsI(Tl) stage of the CHIMERA telescope is used to detect and identify-rays. The high detection efficiency and the sufficient energy resolution guaranteed by CsI(Tl) allows us to use the detector for the study of rare decays. Two examples...

Background: Double charge exchange (DCE) nuclear reactions have recently attracted much interest as tools to provide experimentally driven information about nuclear matrix elements of interest in the context of neutrinoless double- β decay. In this framework, a good description of the reaction mechanism and a complete knowledge of the initial...
