摘要
自然界中的原子核绝大多数是稳定的,形成所谓的β稳定区域.原子序数Z>83的重核和超重核不稳定,可以发生裂变或α,β衰变,寿命总体随着原子序数增加而减小.对于是否存在稳定的高原子序数原子核一直存在争议.本文主要从历史、当前超重元素实验合成状况和量子力学壳模型等方面,讨论"是否存在稳定的高原子序数原子核".
Most of nuclei existing in the nature are stable. For nuclei with proton number Z larger than 83, nuclei become unstable, and decay by fission or emitting ？ and ？ particles. Their lifetimes normally decrease with increasing proton number. It is still a debate whether there exist stable nuclei with high proton numbers. In this article, we discuss whether there exist stable nuclei with high proton numbers, and briefly review the history and current status related to syntheses of superheavy elements.
