Nuclear Data Sheets for A = 175

Abstract

Evaluated spectroscopic data and level schemes from radioactive decay and nuclear reaction studies are presented for all nuclei with mass number A = 175. This evaluation for A = 175 supersedes the earlier one by A.O. Macchiavelli and E. Browne (1993Ma79), published in Nuclear Data Sheets 69, 903 (1993). Highlights of this publication are the following: This evaluation includes the first study (1996Zh03) of 175Er β − decay, which has been used to interpret a predicted ground state doublet in 175Tm. The deep-inelastic reaction studies (1999As05, 1997Le11, and 1997Le10) extended the yrast band of 175Yb to the J π = 41 / 2 − level at 4426 keV. New studies (1994Mi04) of 175Yb β − decay have provided significantly more precise γ-ray intensities. New data (2002Ro17 and 1998To14) from the alpha decay of 179Tl have been used for tentatively assigning spin and parity to 175Au ground and first-excited states. Tentative assignment of 175Hg g.s. is adopted from 176Tl proton decay (2004Ke06).
