Properties of 0⁺ excited states generated by pairing and quadrupole-quadrupole forces in some rare-earth isotopes are investigated. Energies of the 0+ states, probabilities of the E(0) and E(2) transitions, Rasmussen parameters X, and effective cross sections of two-nucleon transfer reactions have been calculated taking into account mixing of the excited states with different K^π values. The contribution of mixing of the excited states underestimates values of the calculated physical quantities.

两核转移反应中 0+ 激发态的数量

研究了一些稀土同位素中由配对和四极-四极力产生的 0 ⁺激发态的性质。考虑到激发态与不同 K ^{π 的}混合，计算了 0+ 态的能量、E(0) 和 E(2) 跃迁的概率、Rasmussen 参数 X 和双核子转移反应的有效截面值。激发态混合的贡献低估了计算物理量的值。
