研究了低通量(~108n/cm2)慢中子对Y系、Bi系及其掺杂高Tc超导体(HTSC)正常态电阻的影响及其机理。实验结果表明,HTSC在低通量慢中子辐照后,正常态电阻R不仅不遵从随辐照通量φn按指数增加的规律,而且还会较大幅度地减小。This work studies the effect and mechanism of slow neutron irradiation of low fluence (~108n/cm2) in normal resistivity of Y and Bi system and the doped high Tc superconductors. The experimental results indicate that the normal resistivity R not only follows the law that R is increasing exponentially with the enhancement of fluence φn, but also decreases greatly after irradiation of slow neutron with low fluence.
