Nuclear processes not only generate the energy and drive the evolution of stars, but also are responsible for the synthesis of the elements in the Universe. Helium (4He, or α) is the second most abundant element after hydrogen, thus α-particle induced reactions such as (α,γ), (α,n) and (α,p) play a crucial role in nuclear astrophysics, especially for understanding stellar helium burning. Direct measurement of the cross sections for these α-capture reactions at stellar energies is greatly hindered because of the strong Coulomb repulsion. Alpha-cluster transfer reaction is a powerful tool for investigation of astrophysical (α,γ), (α,n) and (α,p) reactions since it can preferentially populate the natural-parity states with an α-cluster structure which dominantly contribute to these astrophysical α-capture reactions during stellar helium burning. In this review we summarize the theoretical scheme, the experimental technique, astrophysical applications and the future perspectives of such approach based on α-cluster transfer reactions.

α-团簇转移反应:了解恒星燃烧的工具

核过程不仅产生能量并驱动恒星的演化,而且还负责宇宙中元素的合成。氦气4他,或 α)是仅次于氢的第二最丰富的元素,因此 α-颗粒诱导的反应,例如 αγαñαp在核天体物理学中起着至关重要的作用,尤其是在了解恒星氦燃烧方面。直接测量这些横截面α由于强大的库仑斥力,极大地阻碍了恒星能量下的捕获反应。α-团簇转移反应是研究天体物理学的有力工具αγαñαp 反应,因为它可以优先使用 α-团簇结构,主要促成这些天体物理学 α氦燃烧过程中的捕获反应。在这篇综述中,我们总结了基于这种方法的理论方案,实验技术,天体物理应用以及这种方法的未来前景。α-团簇转移反应。
