The convergence of the close-coupling formalism is studied by expanding the target states in an orthogonal [ital L][sup 2] Laguerre basis. The theory is without approximation, and convergence is established by simply increasing the basis size. We present convergent elastic, 2[ital s], and 2[ital p] differential cross sections, spin asymmetries, and angular-correlation parameters for the 2[ital p] excitation at 35, 54.4, and 100 eV. Integrated and total cross sections as well as [ital T]-matrix elements for the first five partial waves are also given.
