通过中能次级束的核子去除反应，对同位素进行了光谱研究。这项实验的目的是弄清楚位于28次贝壳淬火之间的这个核的能级结构。测量了几个末态的退激射线能量、独占截面和平行出射动量，并与壳层模型、反对称分子动力学框架下的结构计算和eikonal反应计算进行了比较，进一步发展了的能级方案。研究发现，很大一部分单中子击穿反应进入非束缚态，这可能解释了遗漏波强度。
The isotopewas spectroscopically studied via nucleon-removal reactions fromandsecondary beams at intermediate energies. The experiment's aim was to clarify the level structure of this nucleus located in between theand 28 shell quenchings. De-excitation-ray energies, exclusive cross sections, and parallel momentum of outgoingfor several final states were measured and compared to structure calculations in the shell model and antisymmetrized molecular dynamics framework and the eikonal reaction calculation, further developing the level scheme of. It was found that a large fraction of the one-neutron knockout reaction goes into unbound states of, which may explain missing-wave strength.
