摘要

在我所回旋加速器上进行在束

能谱学的研究工作，由于加速器的束流聚焦性能不够理想，造成严重的中子、

本底，使工作存在一定的困难。经采取相应措施后，已初步达到在束

能谱实验的要求，并测得了

Tl的在束

能谱。

Abstract

Because of the poor focusing performance of the beam from our 1.2 m cyclotron

the background gamma ray and neutron are very high in the target hall. Particularly

the high intensity neutron will damage the Ge (Li) detector. A proper shield assembly is used to decrease the interference of such background and the level of background neutron is reduced to 2—3 neutrons/cm

•s. On this condition the in beam

-ray spectra of

199

Tl from the

197

Au (

) reaction have been measured.
