Calculation of Electron Impact Total, Ionization, and Nonbreakup Cross Sections from the3Sand3PStates of Sodium

We present convergent close-coupling calculations of the total, ionization, and nonbreakup cross sections for electron impact of Na $3S$ and $3P$ states. We show that the total and nonbreakup cross sections converge rapidly with increasing target orbital angular momentum $l_{max}$ 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 $l=l_{max}$ 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 $3S$ state is approximately a factor of 2 lower.
