The low-lying positive-parity structures of have been investigated following their population in the reaction at and using a large array of Compton suppressed HPGe clovers as the detection setup. Apart from other spectroscopic measurements, level lifetimes of the states have been extracted using the Doppler shift attenuation method. The level energies and the associated transition probabilities exhibit superlative overlap with the calculations in the framework of the interaction boson approximation and the E(5) model. The nucleus, thus, exemplifies the critical point of phase (shape) transition from the U(5) (spherical vibrator) to the O(6) (-soft rotor) paradigms of nuclear structure.

Kr82 中精确 E(5) 对称性的实验证据
低洼的正平价结构 已经根据他们在该地区的人口进行了调查 反应在 并使用大量康普顿抑制 HPGe 三叶草作为检测装置。除了其他光谱测量外,还使用多普勒频移衰减方法提取了状态的能级寿命。能级能量和相关的跃迁概率与相互作用玻色子近似和 E(5) 模型框架中的计算表现出最高级的重叠。这 因此,原子核举例说明了从 U(5)(球形振动器)到 O(6) 的相(形状)转变的临界点(-软转子)核结构范式。
