Fusion excitation functions for /sup 32/S+ /sup 24,25,26/Mg in the incident energy region E/sub lab/ = 90 to 150 MeV were measured by means of the in-beam ..gamma..-spectroscopy method. In order to suppress background and take into account the contribution of unstable residual nuclei to the in-beam yields of the daughter residues, a computer-controlled chopper system was assembled on the beam line to measure the in-beam and off-beam spectra of the ..gamma.. rays. Detailed comparison was made between the present measurement and the available data obtained by other methods. The measured A and Z distribution was compared with statistical calculations. The fusion excitation functions, which exhibit a change of slope with respect to low energy data, showing evident limitation on the fusion in this energy region, were analyzed in terms of the interaction barrier model and the statistical yrast line model.
