中文摘要：

利用在束γ谱学技术和173Yb（18O,4n）熔合蒸发反应研究了187Pt的高自旋态能级结构.建立了包括3个转动带的187Pt高自旋态能级纲图.基于187Pt周围核结构的系统学和比较带内B（M1）/B（E2）比率的实验值和理论值,建议上述3个转动带的组态分别为11/2＋[615],7/2-[503]和1/2-[521].对各转动带的带交叉频率、顺排增益、旋称劈裂等进行了讨论.

英文摘要：

The high-spin states in ^187Pt have been studied experimentally by means of in-beam γ-ray spectroscopy techniques via the 173Yb（^18O, 4n） fusion-evaporation reaction. The high-spin level scheme of ^18Pt has been established, including three rotational bands. Based on the systematics of level structure in neighboring nuclei and by comparing the experimental and theoretical B（M1）/B（E2） ratios, configurations of 11/2＋ [615], 7/2- [503] and 1/2- [521] have been proposed for the three rotational bands, respectively. Band properties of band crossing frequency, alignment gain and signature splitting have been discussed.
