常用核衰变数据库

为满足工业、农业、地质、探矿、生物、医学、环境保护、能源开发、国防建设以及其它科学研究对放射性核素衰变数据及其衰变纲图的需求, 特增加常用核衰变数据子库，主要包括评价核衰变数据，以及核衰变纲图，共约300个核素。 该子库具有如下特点：（1）普适性和针对性， 数据库中的内容是按实际使用需要确定的；由于所选多数核素的半衰期适中,纲图比较简单,加上收集了用作探测 器刻度的X射线和γ射线标准的核衰变数据,使它可广泛应用于其它核技术应用方面,是一个实用性很强的常用核衰变数据库。（2） 完整性和自洽性，该库提供的核衰变数据种类齐全,包括衰变方式，半衰期，射线能量及强度，分支比,内转换系数,能级自旋与宇称等。数据物理上自洽,可满足多方面的需要。（3）灵活性，使用灵活方便。数据可按不同方式查找、检索,数据信息可以数表和衰变纲图等形式给出。To meet the demands of industrial, agricultural, geological, prospecting, biological, medical, environmental protection, energy development, national defense construction and other scientific research for radionuclide decay data and their decay schemes, a common nuclear decay data sub-database is specially added. This sub-database mainly includes evaluated nuclear decay data and nuclear decay schemes, covering approximately 300 radionuclides. This sub-database has the following characteristics: (1) Universality and pertinence: The content of the database is determined based on actual usage requirements. Since most of the selected radionuclides have moderate half-lives and relatively simple decay schemes, and standard nuclear decay data of X-rays and γ-rays used for detector calibration are also collected, this sub-database can be widely applied in other nuclear technology fields, making it a highly practical common nuclear decay database. (2) Completeness and self-consistency: The nuclear decay data provided by this sub-database covers all necessary categories, including decay modes, half-lives, ray energies and intensities, branching ratios, internal conversion coefficients, spin-parity of energy levels and other related parameters. The data is physically self-consistent and can meet various application needs. (3) Flexibility and convenient usage: The data can be searched and retrieved in multiple ways, and the data information can be presented in forms such as numerical tables and decay schemes.
