摘　　要：概述了利用穆斯堡尔效应开展的固体材料快重离子辐照效应研究的部分结果 ,并对建立在兰州重离子加速器 (HIRFL)Mssbauer spectroscopy study of irradiation effects induced by swift heavy ions in solid materials were briefly presented.Amorphization phenomenon of yttrium iron garnet irradiated by 1 GeV Ar ions has been investigated. For the first time, the nearly complete amorphous state was observed. Stainless steel 316L samples were irradiated with 54 MeV C ions and phase transformation of the samples was observed. HT 9 ferrite steel was irradiated with 510 MeV C ions. Its phase transformation and possible distribution of hyperfine magnetic field were studied. The principle and main characteristic of in beam Mssbauer spectroscopy and the advantage of the research facility of in beam Mssbauer spectroscopy on HIRFL are also introduced. Using the facility, we have observed Mssbauer effect on HIRFL for the first time in China.
