Abstract

168 MeV ⁴⁰Ca ions have been used to Coulomb excite the ground-state band in ¹⁷⁵Lu up to spin $272$ . Lifetimes for levels up to spin $252$ have been determined with DSA and recoil distance methods. Multipole mixing ratios were extracted for the lowest five cascade transitions. Reduced transition probabilities thus deduced in a model independent way were found to be in agreement with the rotational model with Q₀ = 7.42 e · b, g_K = 0.723 and g_R = 0.331.

Nuclear data sheets for A = 175
2004, Nuclear Data Sheets
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).
Nuclear data sheets update for A = 59*
1993, Nuclear Data Sheets
Nuclear structure data pertaining to all nuclei with mass number A = 59 have been compiled and evaluated, and incorporated into the ENSDF data file. Only new or significantly revised data sets are published here, together with all adopted level and adopted γ-ray data information for the A = 59 isobars. This evaluation for A = 59 may be used in conjunction with the previous (full) publication (P. Andersson, L.P. Ekstrom and J. Lyttkens (83An22), published in Nuclear Data Sheets 39, 641 (1983); please note, however, that data sets which are not published here may, nevertheless, appear in revised form in the current ENSDF file.

The ground-state rotational band in <sup>159</sup>Tb
1983, Nuclear Physics, Section A
162 MeV ⁴⁰Ca ions have been used to Coulomb excite the ground-state band of ¹⁵⁹Tb up to spin $252$ . Lifetimes for levels up to spin $252$ have been determined with DSA and recoil distance methods. Multipole mixing ratios for several cascade transitions were extracted from an analysis of γ-ray angular correlation data. Reduced transition probabilities thus deduced in a model-independent way were found to be in agreement with the rotational model with Q₀ = 7.41 ± 0.06 e · b and g_K−g_R = 1.377 ± 0.010.
