本文用Skyrme和体积对能量密度泛函描述了轴对称变形核中准粒子随机相近似（QRPA）的一种新实现。在使用各种测试来证明代码在24,26mg和16o下的准确性之后，我们报告了Skyrme QRPA在重变形核上的第一次完全自一致的应用，计算了172 Yb下几个K π的强度分布。我们给出了能量加权和，γ-振动态和低能K π = 0 +态的性质，以及完整的等矢量E1强度函数。QRPA计算再现了低洼2 +的特性
We describe a new implementation of the quasiparticle random-phase approximation (QRPA) in axially symmetric deformed nuclei with Skyrme and volume-pairing energy-density functionals. After using a variety of tests to demonstrate the accuracy of the code in 24,26 Mg and 16 O, we report the first fully self-consistent application of the Skyrme QRPA to a heavy deformed nucleus, calculating strength distributions for several K π in 172 Yb. We present energy-weighted sums, properties of γ-vibrational and low-energy K π = 0 + states, and the complete isovector E1 strength function. The QRPA calculation reproduces the properties of the low-lying 2 +
