Research on the analytic potential energy function

ZHAI Xue-jun,XUE Bing,YU Chang-feng,GAO Bin (School of Science,Xi′an Polytechnic University,Xi′an 710048,China)  
By using a field equation with a phase factor,an universal analytic potential energy function applied to the interactions between diatomic moleculars or molion is derived,and from the potential energy function many common potential energy curves can be obtained by adjusting a phase factor. By using the potential energy function,the potential energy curves of electronic ground state X2Σ+ of He+2,electronic ground state X′Σ+ of 6LiH,electronic excited state A3Σ+ u of N2,Cu2,Cu-2 etc.are calculated,as a consequence,the computational curves are quite consistent with the experimental curves within the range of fairly high precision.Meanwhile,the force constants of H2 and H+2 are figured out and coincide with the experimental values completely.Finally,the analytic formula expressed by micro parameters for computing Young′s modulus of five kinds of solid materials is given by using the potential energy function.
【Key Words】: potential energy function field equation phase factor derivative renormalization Young′s modulus
