Nuclear structure data pertaining to all nuclei with mass number A=170 have been evaluated, and incorporated into the ENSDF data file. This evaluation supersedes the previous evaluation (Coral M. Baglin), Nuclear Data Sheets 96, 611 (2002), (cutoff date 15 August 2002) and subsequent updates of the ENSDF file for Yb to Dy (cutoff 15 April 2010), Lu (cutoff 8 October 1998), Pt (cutoff 17 February 1999) and Ta, Os (cutoff 7 April 1998). Since the previous evaluation, ¹⁷⁰Gd has been observed and the ground state T_1/2 measured. New excited states have also been observed in the neutron rich ¹⁷⁰Dy. The ground state T_1/2 of ¹⁷⁰Tb has been determined, however, there are currently still no excited states observed in this nucleus. There remains some uncertainty in the ground state and longer-lived isomer in ¹⁷⁰Ir which could warrent further experimental investigation.

已经评估了与质量数A = 170的所有核有关的核结构数据，并将其合并到ENSDF数据文件中。该评估取代了先前的评估（Coral M. Baglin），Nuclear Data Sheets 96，611（2002）（截止日期为2002年8月15日）和随后的ENSDF文件从Yb到Dy的更新（2010年4月15日截止），Lu（截止日期为1998年10月8日），铂金（截止日期为1999年2月17日）和塔斯马尼亚州（截止日期为1998年4月7日）。自从之前的评估以来，已观察到¹⁷⁰ Gd并测量了基态T _1/2。在富含中子的¹⁷⁰ Dy中也观察到了新的激发态。接地线态T _1/2的¹⁷⁰已经确定了Tb，但是，目前在该核中仍未观察到激发态。¹⁷⁰ Ir的基态和更长寿命的异构体仍存在一些不确定性，可能会进一步进行实验研究。
