缺中子的汞同位素是形状共存的经典例子，在低能量下，以不同形状为特征的近简并核状态出现。利用欧洲核子研究中心REX-ISOLDE装置提供的安全能量库仑激发缺中子汞束，研究了均匀质量182 - 188 Hg同位素的电磁结构。的人口，和状态下观察到在所有的核研究。提取了约化E2矩阵元耦合布居的yraast和non-yraast态，包括它们的相对符号。这些是形状共存的敏感探针，可用于验证核模型。实验结果进行了讨论，在两种不同的配置混合，并与三种不同的模型计算：超越平均场模型，相互作用玻色子模型与配置混合和一般玻尔哈密顿量进行了比较。观察到与实验的部分一致性，暗示在理论描述中缺少成分。
The neutron-deficient mercury isotopes serve as a classical example of shape coexistence, whereby at low energy near-degenerate nuclear states characterized by different shapes appear. The electromagnetic structure of even-mass182-188Hg isotopes was studied using safe-energy Coulomb excitation of neutron-deficient mercury beams delivered by the REX-ISOLDE facility at CERN. The population of,andstates was observed in all nuclei under study. ReducedE2 matrix elements coupling populated yrast and non-yrast states were extracted, including their relative signs. These are a sensitive probe of shape coexistence and may be used to validate nuclear models. The experimental results are discussed in terms of mixing of two different configurations and are compared with three different model calculations: the Beyond Mean Field model, the Interacting Boson Model with configuration mixing and the General Bohr Hamiltonian. Partial agreement with experiment was observed, hinting to missing ingredients in the theoretical descriptions.
