Abstract

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 α and β 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.
