对变形的偶偶核170Er激发态的全部实验数据进行了批判性分析。通过将来自相关(n，n‘γ)反应的伽马射线光谱与来自其他过程的数据进行比较，有可能揭示新的Kπ=0−和2−谱带，并建立新的能级，包括已知谱带的旋转能级，并考虑转动惯量。在Nilsson方案和准粒子-声子模型的基础上研究了170Er的激发态结构。
A critical analysis of the entire body of available experimental data on the excited states of the deformed even-even nucleus 170Er is performed. By contrasting the spectrum of gamma rays from the relevant (n, n′γ) reaction against data from other processes, it is possible to reveal new Kπ=0− and 2− bands and to establish new levels, including rotational levels of known bands, with allowance for the moments of inertia. The structure of the excited states of 170Er is investigated on the basis of the Nilsson scheme and of the quasiparticle-phonon model.
