我们报告的测量的第一标准状态和通过在束射线光谱。感兴趣的原子核是在入射能量为。实验是在RIKEN放射性同位素束工厂进行的，使用了DALI射线探测器阵列和新型MINOS设备，即一种与顶点跟踪器相结合的厚液氢靶。分别对Cr和Fe的偶-偶同位素观察到一个低能平台和能量随中子数的变化。最先进的壳层模型计算与修改后的Lenzi-Nowacki-Poves-Sieja（Lizi）相互作用在thevalence空间再现的观察。壳层模型的解释表明，对于更多的富中子同位素，反转岛向。
We report on the measurement of the firstandstates ofandvia in-beam-ray spectroscopy. The nuclei of interest were produced byreactions at incident energies of. The experiment was performed at the Radioactive Isotope Beam Factory, RIKEN, using the DALI-ray detector array and the novel MINOS device, a thick liquid hydrogen target combined with a vertex tracker. A low-energy plateau ofandenergies as a function of the neutron number was observed forandfor even-even Cr and Fe isotopes, respectively. State-of-the-art shell model calculations with a modified Lenzi-Nowacki-Poves-Sieja (LNPS) interaction in thevalence space reproduce the observations. Interpretation within the shell model shows an extension of the island of inversion atfor more neutron-rich isotopes towards.
