We show that the new superconductor has a rather high upper critical field of about 54 T. A clear signature of superconducting gap opening below T$_c$ was observed in the far-infrared reflectance spectra, with 2$\\Delta/\\textit{k}T_c\\approx$3.5-4.2. Furthermore, we show that the new superconductor has electron-type conducting carrier with a rather low carrier density.","authors_text":"D. Wu, G. F. Chen, G. Li, H. Q. Yuan, J. Dong, J. L. Luo, J.
