We report observations from the ({ital p},{ital n}) reaction on {sup 12}C at 135 MeV. The experiment was performed with the beam-swinger neutron time-of-flight system at the Indiana University Cyclotron Facility. Neutrons were detected in large-volume plastic scintillation detectors located in three detector stations at 0{degree}, 24{degree}, and 45{degree} with respect to the undeflected beam line; the flight paths were 91 m, 91 m, and 74 m, respectively. Overall time resolutions of about 825 ps provided energy resolutions of about 350 keV in the first two stations and about 425 keV in the third station. The angular distributions for states with excitation energies up to 10 MeV are presented and comparisons are made with DWIA calculations that use one-body density matrices from 0{h_bar}{omega} and 1{h_bar}{omega} shell-model calculations. New information is deduced on the excitation energies, widths, and spin-parity assignments for several energy levels of {sup 12}N. {copyright} {ital 1996 The American Physical Society.}
