In反冲在银中引起辐射损伤的初步研究结果。

分别以剂量率为0.5×10

），能量为26MeV的α粒子，在室温和液氮温度下轰击银箔，观察到由辐射损伤引起的四极相互作用与剂量率、辐照温度、退火温度有关。在液氮温度小剂量率的辐照样品研究中，我们测量到一个“恒定”的四极相互作用尖频率ω。为82MHz，在淬火效应的观察中，得到的四极尖频为115MHz．室温下以大剂量率和小剂量率辐照的实验中，均未见到四极相互作用尖频。

Abstract

In this paper

the observation of radiation damage in silver is presented. The radiation damage in silver is induced by

111

In ions that have been implanted into cubic Ag lattice following (α

) reaction.

The silver foils were irradiated with 26MeV

particles under room temperature and liquid nitrogen temperature respectively

the dose rates were 0.5×10

α/cm

•s and 1.2× 10

α/cm•s. The radiation damage induced by nuclear collision have been studied corresponding to the dose rate and radiated temperature.

In the experiments with samples irradiated under liquid nitrogen temperature by low dose rate

we have observed a definite sharp quadrupole frequency

± 82MHz. In quenching experiment

we get ω

±116MHz. In the measurement with samples irradiated under room temperature

we haven't seen any sharp frequency wether using large dose rate or low dose rate.
