首次在298 K下对SmFeAsO多晶样品进行了正电子湮没寿命谱（帕尔斯）测量.得到了151 μ 6 ps和290 μ 3 ps两个寿命分量。根据双态俘获模型，
Positron annihilation lifetime spectroscopy (PALS) measurements of SmFeAsO polycrystalline sample were first carried out at 298 K. Two lifetime components of 1516 ps and 2903 ps were obtained. According to two-state capture model, the free annihilation
