Abstract
By selecting B-spline basis functions systematically in variational calculations, we obtain the accurate wavefunctions and energies for n1,3 P and n1,3D states of He for n1,3P, it is indistinguishable between our present and previous results. The present results were obtained with smaller number of basis functions. We can therefore use the accurate wavefunctions to calculate oscillator strengths for the transitions mS-nP, mP-nD, m, n1P and m1D (or between 11S and m1P) for m<or=9. Our results also agree with some recent accurate experimental results as good as those of Kono and Hattori.Keywords
