The distribution of proton-hole strengths in the (2s, 1d)-shell of 35Cl, 37Cl and 39Cl

Inclusive and exclusive electron scattering data analysis from Jefferson Lab experiment E12-14-012

“…More deeper-lying shells-1p 1/2 , 1p 3/2 , and 1s 1/2 -were not probed by the past experiments [163,164]. Their E α values, as well as the widths σ α for all shells, are determined to provide a reasonable description of the missing-energy distributions obtained in this experiment.…”

“…(6.11), because a few spectroscopic lines typically correspond to a given spin-parity state. To overcome this issue and identify the dominant lines, we rely on the spectroscopic strengths determined in past direct pick-up experiments such as A( 21 H, 3 2 He) for argon [163] and titanium [164]. lines contributing-can be expected to lend itself well to the approximation by a single distribution of finite width.…”

“…lines contributing-can be expected to lend itself well to the approximation by a single distribution of finite width. To determine its peak position, in addition to the experimental data [163,164], we use the theoretical analyses of Refs. [165,166] as guidance.…”

Determination of the argon spectral function from (e,e'p) data

“…including constraints on the position of the topmost energy levels from previous experimental results [28,[37][38][39], summarized in Table VI.…”

Investigation of the ground-state spin inversion in the neutron-rich Cl47,49 isotopes

“…A similar comparison may be performed on the odd partners, potassium and chlorine isotopes. With (d, 3 He) transfer experiments on even argon isotopes [17,18], the 3/2 + 1 ground state and 1/2 + 1 first excited state were identified in 37,39 Cl as proton-hole states with large spectroscopic factors exhausting most of the corresponding strength. A sharp decrease was observed for the energy difference from 37 Cl to 39 Cl, suggesting a possible spin inversion and a 1/2 + 1 ground state for more exotic isotopes.…”
