摘要
An accurate method combining the spheroidal coordinate and B-spline for H2+is tested.The equilibrium distances and the total energies of the states with|m|≤4 for the magnetic field strengthγ=1 are given and compared with those obtained using different methods.Taking the advantages of the spheroidal coordinate and B-spline,a 10^(-9)–10^(-12)accuracy is obtained for the energies of the states with|m|≤3,and a 10^(-5)–10^(-7)accuracy for the equilibrium distances.There are seven significant digits for the energy of the state 1γg and four significant digits for 1γu,which are consistent with those obtained by the high-precision method.There are three significant digits for the equilibrium distances of the 1γg,u states,which are consistent.
