With new experimental information on nuclei far from stability being available, a systematic investigation of excitation energies and electromagnetic properties along the $N=10, 11, 12$ isotones and $Z=10, 11, 12$ isotopes is presented. The experimental data are discussed in the context of the appearance and disappearance of shell closures at $N=Z=8,14,16,20$, and compared to an effective-interaction approach applied to neutrons and protons in $d_{5/2}^{2,3,4}$ configurations. In spite of its simplicity the model is able to explain the observed properties.

Hadron freeze-out conditions in high energy nuclear collisions
讨论了从AGS/SPS到RHIC强子冻结条件的系统趋势。在RHIC碰撞中最有趣的结果是,系统确实接近净重子自由,横向膨胀比在AGS/SPS能量下的碰撞强得多。为了了解集体速度的趋势,有必要在$\sqrt{s_{NN}} = 20 - 200 GeV, is important. In addition, systematic studies on the anisotropy parameter $ v_2 $ and the transverse momentum distributions of $ Ω、$ and $ J /Ω $之间进行能量扫描,因为它们将有助于确定集体是否在部分子阶段发展。
Freeze-out configuration properties in the 197Au + 197Au reaction at 23 AMeV
对23 AMeV的197 Au +197 Au反应实验数据进行了分析,目的是寻找奇异核构型的特征,如环形物体。的ETNA代码专门寻找这样的配置,并与QMD模型的预测的实验数据进行比较。一个新的标准选择事件可能导致形成的异国情调的冻结出的配置,“效率因子”,进行了测试。实验数据和模型预测之间的比较可能表明形成的平面/环形核系统。
