Abstract A differentially pumped windowless {sup 20}Ne gas target and a {sup 20}Ne beam produced with the ATLAS accelerator at Argonne National Laboratory were used to measure angle-averaged excitation functions for binary decay of {sup 20}Ne+{sup 20}Ne into low-lying states of {sup 20}Ne+{sup 20}Ne and {sup 24}Mg+{sup 16}O, in the region of excitation energy in {sup 40}Ca from 51.4 to 58.2 MeV ({sup 20}Ne beam energies from 61.8 to 75.4 MeV). The {sup 20}Ne+{sup 20}Ne mass partition displays little correlated structure and there exists no evidence of intermediate width resonances in these channels with branching ratios comparable to those seen in the {sup 24}Mg+{sup 24}Mg system. Angular distributions for the elastic channel are consistent with those obtained using optical-model calculations. The exictation functions for the low-lying channels in {sup 24}Mg+{sup 16}O do contain some structures, with widths varying from 400 to 800 keV in the c.m. system.
