摘要

著名的7.65兆电子伏特\({}^{+}_{2}\)霍伊尔态\({}^{12}\) C一直吸引着大量的关注。这种状态具有稀释的3 \(\alpha\)构型，在核合成中起重要作用。问题是在其他4个\(N\)原子核中是否有类似霍伊尔态的状态。有可能\({}^{20}\) Ne中的\(\alpha\) -cluster 0 \({}^{+}_{2}\)状态可以被认为是\({}^{12}\) C的7.65-MeV 0 \({}^{+}_{2}\) Hoyle状态的类比。

Possible Analogs of the Hoyle State in Heavier 4\({N}\) Nuclei

The famous 7.65-MeV 0\({}^{+}_{2}\) Hoyle state of \({}^{12}\)C is always attracting plenty attention. This state has dilute 3\(\alpha\) configuration and plays important role in nucleosynthesis. Question is if there are states analog to the Hoyle state in other 4\(N\) nuclei. It is possible that \(\alpha\)-cluster 0\({}^{+}_{2}\) state in \({}^{20}\)Ne can be considered as an analog of the 7.65-MeV 0\({}^{+}_{2}\) Hoyle state of \({}^{12}\)C.

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
