We present the results of an 83-term, 180-level intermediate-coupling frame-transformation (ICFT) R-matrix close-coupling calculation of the electron-impact excitation of boron-like Ne5+. All levels of the 2s22p, 2s2p2, 2p3, 2s23�, 2s24�, 2s2p3�, 2p23�, 2s2p4s, 2s2p4p, and 2s2p4d configurations are included in the close-coupling expansion. This sizable calculation was performed using our new ICFT R-matrix codes designed for distributed-memory parallel computers. We compare our results from this calculation with those from our 11-term 20-level ICFT calculation and an earlier eight-term 15-level R-matrix calculation. Here we describe the nature of these calculations and present radiative rates and effective collision strengths for a selected number of the 16 110 transitions resulting from this work. The full set of data is available at the Oak Ridge National Laboratory Controlled Fusion Atomic Data Center Web site.
