摘要

采用康普顿抑制谱仪和三参数γ -γ -T符合系统对188Re衰变进行了仔细的研究。数据分析表明

810keV、14 6 3keV、1936keV、5 5 7keV、186 7keV、2 0 2 2keV这 6条γ射线以及 14 4 3keV、1936keV、2 0 2 2keV 3条能级是存在的。同时

在单谱、反康谱及符合谱中发现了 1982 .5± 0 .2keV、184 2 .5± 0 .2keV、182 8.2± 0 .1keV、110 3.7± 0 .4keV、10 86 .13± 0 .0 3keV、979.2 9± 0 .0 8keV、82 6 .90± 0 .0 2keV、30 9.6 0± 0 .0 4keV共 8条新的γ射线

并确定了 1982 .5keV、182 8.2keV、30 9.6keV共 3条新能级。实验数据用ENSDF（EvaluatedNuclearStructureDataFile）进行了详细分析

并给出了修改后的衰变纲图。

Abstract

The γ-ray spectra of 188 Re decay have been studied by using a compton-suppressed spectrometer and a three parameters γ-γ-T coincidence system. Experimental data analysis demonstrates that six γ-rays at 810

1867 and 2022keV and 1443

1936 and 2022keV three levels are confirmed again. Eight new γ-rays at 1982.5±0.2

1842.5±0.2

1828.2±0.1

826.90±0.02

309.60±0.04keV

tree new levels at 1982.5

1828.2

309.60keV have been found in the γ singles

Compton-suppressed spectra and coincidence spectra .The experimental data were analysed by ENSDF (Evaluated Nuclear Structure Data File) in detail and the modified decay scheme was presented.
