Nuclear data sheets for A = 171

Abstract

The experimental data for nuclei in the mass chain A = 171 have been examined, and the results summarized. The compilers have deviated somewhat from standard Nuclear Data Sheet practices. They have done so 1) by excluding some symbols normally included in drawings (e.g., coincidence dots) 2) by minimizing the effort devoted to the data per se, and concentrating on only that data needed to summarize the present status of the physics involved. Of the ten nuclei identified thus far in this mass chain, the data yield considerable information pertaining to the low—lying structure of 171Yb and 171Lu. For these nuclei, many of the expected Nilsson states (and rotational bands) have been established. The probable decay of 171Ta (supposedly 7/2 +[404]) to members of the 1/2 −[521] band in 171Hf is somewhat puzzling. It is hoped that the present compilation might serve as a basis for choosing definitive experiments that would augment our knowledge of nuclei in this mass chain.
