“…For the α-transfer measurement, highly enriched 22 Ne gas (enrichment > 99%) was pressurized to 0.2 atm in a gas-cell using a gas handling system [67]. The cell body was machined from copper and the gas was filled into a volume measuring 44 mm by 14 mm by 10 mm.…”

“…The contribution from nat Si was subtracted using a nat Si target. For the 20 Ne target, a cooling gas target system was used [32,33]. The isotopically enriched 20 Ne gas with a purity of 99.95% was filled into the gas cell and cooled by liquid N 2 in order to increase the target density.…”

We systematically measured the differential cross sections of inelastic α scattering off self-conjugate A = 4n nuclei at two incident energies E α = 130 MeV and 386 MeV at Research Center for Nuclear Physics, Osaka University. The measured cross sections were analyzed by the distorted-wave Born-approximation (DWBA) calculation using the single-folding potentials, which are obtained by folding macroscopic transition densities with the phenomenological αN interaction. The DWBA calculation with the density-dependent αN interaction systematically overestimates the cross sections for the ΔL = 0 transitions. However, the DWBA calculation using the density-independent αN interaction reasonably well describes all the transitions with ΔL = 0-4. We examined uncertainties in the present DWBA calculation stemming from the macroscopic transition densities, distorting potentials, phenomenological αN interaction, and coupled channel effects in 12 C. It was found that the DWBA calculation is not sensitive to details of the transition densities nor the distorting potentials, and the phenomenological density-independent αN interaction gives reasonable results. The coupled-channel effects are negligibly small for the 2 + 1 and 3 − 1 states in 12 C, but not for the 0 + 2 state. However, the DWBA calculation using the density-independent interaction at E α = 386 MeV is still reasonable even for the 0 + 2 state. We concluded that the macroscopic DWBA calculations using the density-independent interaction are reliably applicable to the analysis of inelastic α scattering at E α ∼ 100 MeV/u.

“…The solid targets, made from isotopically-enriched materials, were of nominal thicknesses between ∼400-500 µg/cm 2 supported on carbon foils of thickness 100 µg/cm 2 . For the Xe isotopes, the Grand Raiden gas-target system was used [31]. The target was of depth (along the beam line axis) of ∼8 mm.…”

The change in the configuration of valence protons between the initial and final states in the neutrinoless double β decay of Together with our recent determination of the relevant neutron configurations involved in the process, a quantitative comparison with the latest shell-model and interacting-boson-model calculations reveals significant discrepancies. These are the same calculations used to determine the nuclear matrix elements governing the rate of neutrinoless double β decay in these systems.
