Detailed -ray spectroscopy of the exotic neon isotope $^{28}$ Ne has been performed using the one-neutron removal reaction from $^{29}$ Ne. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$ Ne and the negative-parity states are identified for the first time. The measured partial cross sections and momentum distributions reveal a significant intruder p-wave strength providing evidence of the breakdown of the N = 20 and N = 28 shell gaps. Only a weak, possible f-wave strength was observed to bound final states. Large-scale shell-model calculations with different effective interactions do not reproduce the large p-wave and small f-wave strength observed experimentally, indicating an ongoing challenge for a complete theoretical description of the transition into the island of inversion along the Ne isotopic chain.

Epitaxial Ba $_{0.5}$ Sr $_{0.5}$ TiO thin films were prepared on Nb-doped SrTiO (100) substrates by the pulsed laser deposition technique and were studied by measuring the Ti 2p 3d resonant photoemission spectra in the valence-band region, both at room temperature and low temperature. The results demonstrated an abrupt variation in the spectral structures between 2.8 nm (7 ML) and 2.0 nm (5 ML) Ba $_{0.5}$ Sr $_{0.5}$ TiO films, suggesting that there exists a critical thickness for phase change in the range of 2.0-2.8 nm.

The electronic structures of Sr $_{2}$ FeMoO $_{6}$ (SFMO) and Ba $_{2}$ FeMoO $_{6}$ (BFMO) double perovskites have been investigated using Fe 2p-3d resonant photoemission spectroscopy (PES) and the Cooper minimum in the Mo 4d photoionization cross section. The states close to the Fermi level are found to have a strongly mixed Mo–Fe t $_{2g}$ character, indicating that the Fe valence is far from pure 3+. The Fe 2p $_{3/2}$ x-ray absorption spectroscopy spectra reveal the mixed-valent Fe $^{3+}$ –Fe $^{2+}$ configurations, and a larger Fe $^{2+}$ component for BFMO than for SFMO, suggesting an operative double exchange interaction. The valence-band PES spectra reveal good agreement with the local-spin-density-approximation (LSDA+U) calculation.
