Nuclear Data Sheets for A = 170

Nuclear structure data from radioactivity and nuclear reaction measurements are summarized, and adopted level properties are presented. The present compilation is based on information available through December 1974. The compilation consists of drawings which display the bulk of the data followed by Summary Sheets which present the adopted level properties in greater detail and, where practical, the data on which they are based. The third section consists of supplementary Data Sheets for those nuclei requiring extensive data tabulations. The 170Lu(epsilon+β+)170Yb decay scheme is quite complex. Only the lowest portion is reproduced in detail in this compilation. Complete data for the higher levels have been entered in the Evaluated Nuclear Structure Data File (ENSDF) maintained by the Nuclear Data Group, and a complete decay scheme is available upon request.
