Abstract

The data on theϑ lab=7° excitation functions of12C(15N,4He)23Na reaction betweenE cm=9.42 and 17.33 MeV for 28 states upto an excitation energy of 8.940 MeV in23Na have been subjected to statistical analysis. In addition to statistical fluctuations, the results of the analysis indicate the existence of non-statistical structures atE cm=10.66, 10.93, 11.38, 12.62, 13.16, 15.32 and 16.18 MeV.
