“…The data for 27 S were collected for 95.3 h, excluding the time between each run. The present statistics on 27 S is much higher than the statistics of ∼1 × 10 4 achieved by Canchel et al [48] and that of 1267 achieved by Janiak et al [18], so the reliability of the determination or restriction of the nuclear structure information can be improved since the decay events can be observed with higher statistics in this work.…”

“…β-decay spectroscopic study has proved to be a powerful tool to obtain the structure information adjacent to the drip line, as well as an excellent and stringent test of the accuracy of shell-model predictions far from the valley of stability. As the degree of asymmetry preserves important information on the nuclear structure of the states involved, it is desirable to investigate the possible mirror asymmetry in the case of 27 S → 27 P and 27 Na → 27 Mg [18]. To provide a better understanding of the nature of isospin-symmetry breaking, high precision measurements of β decays should be extended to more nuclides.…”

“…Canchel et al measured the 27 S decay by using a similar method, and high-energy β-delayed proton branches were found [48]. Recently, Janiak et al identified two low-energy proton transitions by using an optical time projection chamber [18]. The large β-decay energy of 27 S implies that many decay channels are open.…”

“…As Janiak et al pointed out, their experiment of 27 S based on a time projection chamber technique was preferred for the clear identification of decay channels and for the precise determination of their absolute branching ratios. The exact energies of the relevant resonances and the probability ratios of γ -to-proton emission can be established accurately using a complementary detector array, which refers to several silicon detectors surrounded by germanium detectors [18].…”

Background: β-decay spectroscopy provides valuable information on exotic nuclei and a stringent test for nuclear theories beyond the stability line. Purpose: To search for new β-delayed protons and γ rays of 25 Si to investigate the properties of 25 Al excited states. Method: 25 Si β decays were measured by using the Gaseous Detector with Germanium Tagging system at the National Superconducting Cyclotron Laboratory. The protons and γ rays emitted in the decay were detected simultaneously. A Monte Carlo method was used to model the Doppler broadening of 24 Mg γ-ray lines caused by nuclear recoil from proton emission. Shell-model calculations using two newly-developed sd-shell Hamiltonians, USDC and USDI, were performed. Results: The most precise 25 Si half-life to date has been determined. A new proton branch at 724(4) keV and new proton-γ-ray coincidences have been identified. Three 24 Mg γ-ray lines and eight 25 Al γ-ray lines are observed for the first time in 25 Si decay. The first measurement of the 25 Si β-delayed γ ray intensities through the 25 Al unbound states is reported. All the bound states of 25 Al are observed to be populated in the β decay of 25 Si. Several inconsistencies between the previous measurements have been resolved, and new information on the 25 Al level scheme is provided. An enhanced decay scheme has been constructed and compared to the mirror decay of 25 Na and the shell-model calculations. Conclusions: The measured excitation energies, γ-ray and proton branchings, log f t values, and Gamow-Teller transition strengths for the states of 25 Al populated in the β decay of 25 Si are in good agreement with the shell model calculations, offering gratifyingly consistent insights into the fine nuclear structure of 25 Al.

“…3.3. β-delayed proton emission from 26 P and 27 S Delayed emission of protons following β decay of neutron-deficient nuclei 26 P and 27 S was investigated [23] at the ACCULINNA separator. Ions of interest, identified in flight, were implanted into the active volume of the gaseous optical time-projection chamber, which allowed us to record tracks of charged particles emitted in the decay.…”

The fragment separator ACCULINNA-2 has been constructed, approved by the Programme Advisory Committee (PAC) and commissioned in the G.N. Flerov Laboratory of Nuclear Reactions (JINR, Dubna) in 2017. It was tested with the 15 N beam at the energy of 49.7 MeV/nucleon. The secondary beams 6 He and 12 Be produced in the beryllium target were obtained with purities and intensities predicted by the code LISE++. Here, we list the most meaningful and challenging experiments on the light dripline nuclei at ACCULINNA, which should be clarified at ACCULINNA-2: (i) the search for the minor 2p-decay branch of the first excited state of 17 Ne, the Γ 2p /Γ γ width ratio; (ii) study of break down of the shell closure in the doubly magic 10 He in the 3 H(8 He,p) 10 He reaction; (iii) study of the β-delayed proton emission in 26 P and 27 S, which offers insight into the structure of the initial and the final states of these exotic nuclei. Among the first-day experiments is a study of the low-energy resonance states of 7 H anticipated for the 4n decay.
