The 1s(2)2s(2)2p(4) (3)P(e), (1)D(e), and (1)S(e) states of Ne(2+) are included as residual-ion states to assess the influence of interference between photoionization channels associated with these thresholds. The harmonic spectrum is well approximated by calculations in which only the (3)P(e) and (1)D(e) thresholds are taken into account, but no satisfactory spectrum is obtained when a single threshold is taken into account.
