C-12(P,N)N-12 REACTION AT 135 MEV

We report observations from the (p,n) reaction on C-12 at 135 MeV. The experiment was performed with the beam-swinger neutron time-of-flight system at the Indiana University Cyclotron Facility. Neutrons were de tected in large-volume plastic scintillation detectors located in thre e detector stations at 0 degrees, 24 degrees, and 45 degrees with resp ect to the undeflected beam line; the flight paths were 91 m, 91 m, an d 74 m, respectively. Overall time resolutions of about 825 ps provide d energy resolutions of about 350 keV in the first two stations and ab out 425 keV in the third station. The angular distributions for states with excitation energies up to 10 MeV are presented and comparisons a re made with DWIA calculations that use one-body density matrices from Ono and <1(h)over bar omega> shell-model calculations. New informatio n is deduced on the excitation energies, widths, and spin-parity assig nments for several energy levels of N-12.
