Experimental nuclear structure and decay data are evaluated for 13 known nuclides of mass number A=63 (Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se). Detailed evaluated level properties and related information are presented and recommended spectroscopic parameters are provided, combining all the data from various reactions and decays. No excited state has been observed for 63Ti, 63As and 63Se, among which the first two nuclides have no halflife, decay modes and spin-parity being measured and reported yet. The ground-state spins and/or parities of 63V, 63Cr, 63Mn, and 63Ge still have not been definitely determined and information for excited states in these nuclides plus 63Fe is limited. Information for 63Ga is mostly from one measurement and no data for 63Ge ε+β+ decay have been measured while this decay mode (%100) of the 63Ge parent is known. The 63Cu nuclide is the most extensively studied via more than 28 different reactions and decays, followed by 63Zn and 63Ni. Among all those nuclides, only 63Cu has a complete radioactive decay scheme. This work supersedes earlier full evaluations of A=63 published by 2001Ba27, 1991Ki10, 1979Au10, and 1975Au03.

A=63 等压线的核结构和衰变数据



评估了 13 种质量数为 A=63 的已知核素(Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ga、Ge、As、Se)的实验核结构和衰变数据。提供了详细评估的能级特性和相关信息,并提供了推荐的光谱参数,结合了来自各种反应和衰变的所有数据。未观察到 63Ti、63As 和 63Se 的激发态,其中前两个核素没有半衰期、衰变模式和自旋奇偶性尚未测量和报道。63V、63Cr、63Mn 和 63Ge 的基态自旋和/或奇偶性仍未确定,并且这些核素中激发态加上 63Fe 的信息是有限的。63Ga 的信息主要来自一次测量,没有测量到 63Ge ε+β+ 衰变的数据,而 63Ge 母体的这种衰变模式 (%100) 是已知的。63Cu 核素是通过超过 28 种不同的反应和衰变进行最广泛的研究,其次是 63Zn 和 63Ni。在所有这些核素中,只有 63Cu 具有完整的放射性衰变方案。这项工作取代了 2001Ba27、1991Ki10、1979Au10 和 1975Au03 发表的对 A=63 的早期完整评估。
