We present convergent close-coupling calculations of the total, ionization, and nonbreakup cross sections for electron impact of Na 3[ital S] and 3[ital P] states. We show that the total and nonbreakup cross sections converge rapidly with increasing target orbital angular momentum [ital l][sub max] used in the close-coupling expansion. The total ionization cross section is less rapidly convergent, and typically has the largest partial contribution from ionization of the [ital l]=[ital l][sub max] states. The total cross sections and total ionization spin asymmetries are in excellent quantitative agreement with experiment. However, the total ionization cross section from the 3[ital S] state is approximately a factor of 2 lower.
