With the optimized tensor interactions, the binding energies of spherical or weakly deformed nuclei with A=54-228\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$A=54{-}228$$\end{document} are studied systematically. The present results show that the global effect of tensor interaction is attractive and systematically increases the binding energies of all these nuclei and makes the nuclei more bound. The root mean squared deviation of the calculated binding energies from the experimental values is significantly improved by the optimized tensor interactions, and the contribution of the tensor interaction to the binding energy is estimated.
