研究了核反应速率对核性质变化的敏感性。靶核的范围从质子到中子滴线为10 <$Z 183。所考虑的反应是由强相互作用介导的核子和α诱导反应。给出了在目标基态上发生的反应对总恒星速率的贡献。一般依赖于各种输入量进行了讨论。此外，灵敏度的实验室截面的核子，α和γ诱导的反应，使我们能够估计截面测量的影响。最后，建议的程序，探索和改善反应速率的不确定性，使用目前的敏感性数据进行了概述。
Sensitivities of nuclear reaction rates to a variation of nuclear properties are studied. Target nuclei range from proton- to neutron dripline for 10 ⩽ Z ⩽ 83. Reactions considered are nucleon- and α-induced reactions mediated by strong interaction. The contribution of reactions occurring on the target ground state to the total stellar rate is also given. General dependencies on various input quantities are discussed. Additionally, sensitivities of laboratory cross-sections of nucleon-, α-, and γ-induced reactions are shown, allowing us to estimate the impact of cross-section measurements. Finally, recommended procedures to explore and improve reaction rate uncertainties using the present sensitivity data are outlined.
