The first-excited, J π = 2 + state of 16 Ne at E * = 1.69(2) MeV is well populated in neutron knockout reactions with a 17 Ne beam and the correlations between the momenta of the three final fragments following 2p decay were measured. The correlation pattern showed aspects of both sequential and diproton-like decay, which were reproduced in three-body 14 O+p+p calculations. These calculations suggest that interference between these processes is responsible for the observed features which can be described in terms of a "tethered decay mechanism". The intrinsic width of this state was constrained to be from 100 to 250 keV. Higher excited states populating the 13 N+p+p+p exit channel were found at E

“…This provides a simple way for estimates of dominant orbitals. Studies of the TES were recently extended to nuclei with an even number of "valence" nucleons, which allowed for estimates of nuclear configuration mixing [26]. The TES effect is responsible for energy anomalies in the nuclei near and especially beyond the proton drip line [27].…”

Previously unknown isotopes30 Ar and 29 Cl have been identified by measurement of the trajectories of their in-flight decay products 28 S þ p þ p and 28 S þ p, respectively. The analysis of angular correlations of the fragments provided information on decay energies and the structure of the parent states. The ground states of 30 Ar and 29 Cl were found at 2.25 þ0.15 −0.10 and 1.8 AE 0.1 MeV above the two-and one-proton thresholds, respectively. The lowest states in 30 Ar and 29 Cl point to a violation of isobaric symmetry in the structure of these unbound nuclei. The two-proton decay has been identified in a transition region between simultaneous two-proton and sequential proton emissions from the 30 Ar ground state, which is characterized by an interplay of three-body and two-body decay mechanisms. The first hint of a fine structure of the two-proton decay of 30 Ar Ã ð2 þ Þ has been obtained by detecting two decay branches into the ground and first-excited states of the 28 S fragment.

Effects of the Coulomb interaction on parameters of resonance states in mirror three-cluster nuclei

et al. 2020

We investigate how the Coulomb interaction affects the energy E and width Γ of resonance states in mirror nuclei. We employ a three-cluster microscopic model to determine position of resonance states in two-and three-body continua. Two parameters are introduced to quantify effects of the Coulomb interactions. As the energy and width of the corresponding resonance states of mirror nuclei are displayed on an E-Γ plane, these parameters determine a rotation and a dilatation. With the help of these parameters we found resonance states with strong, small and medium effects of the Coulomb interaction. We also found two different scenarios of the motion of resonance states due to the Coulomb interaction. The first standard (major) scenario represent resonance states with the larger energy and larger width than their counterparts have. The second rear scenario includes resonance states with the larger energy but smaller width.
