摘　　要：基于固定核近似原理,利用R矩阵方法和分子的R矩阵程序计算了在4-20 eV能量范围内电子被水分子弹性散射的总碰撞截面,同时讨论了R矩阵半径的取值对总截面的影响.并将结果与实验值及其它理论计算作了比较,结果显示这种计算方法对于电子分子碰撞是很有效的.The R-matrix method and the UK molecular R-matrix codes are used in this work to calculate total （integral） cross sections of electrons elastic scattering from H2O molecule in quite low energy range 4-20 eV and the scattering calculations are performed within the fixed-nuclei approximation. Then the effect of radius of R-matrix sphere to the results is discussed. Cross sections are compared with previous result and also experiments and the results are in good agreement with experimental ones.
