LETTER TO THE EDITOR

We considered the Harris-Nesbet variational method for an accurate calculation of phase shifts in positron-He+ collisions. Calculations have been carried out for L = 0, 1, 2, 3, 4, 5, 6 partial waves. Very accurate results of phase shift have been obtained for the first time. The accuracy has been double-checked by carrying out the calculations with the use of different large-coupling schemes. We compare our results with those available in the literature.
