The 48Ca(p, n) 48Sc reactions to the first 11 excited states in 48Sc have been studied as a function of angle and proton energy from 4.03 to 5.63 MeV. Absolute cross sections (±25%) have been obtained using a calibrated, time-of-flight detection system. The cross sections are observed to have random fluctuations in accordance with the Ericson fluctuation theory. There is no indication of any direct reaction contributions to the cross sections. The average angular distributions are symmetric about 90°. The coherence energy Γ is observed to be ≦ 9 keV at 15 MeV excitation in 49Sc. Autocorrelation analysis of the cross sections for exciting the third to 11th excited states of 48Sc leads to probable spins of (3,4), (1,2), 2, (1,2), 1, (2,3), 2 and 0, respectively.
