Abstract：
The statistical emission of the 35MeV/u ⁴⁰Ar+¹⁹⁷Au was studied. Several silicon △E1+ silicon △E2+CsI(Tl) telescopes with good particle identification and lower energy thresholds were used to collect the experimental data. For the backward angle emission events, the slope nuclear temperature parameters and the isotope nuclear temperature parameters, which were extracted from the slope of energy spectra and double isotope yield ratios of the reaction products respectively, were nearly the same. The slope temperatures were slightly higher than the isotope temperatures. The reliability of the method to extract nuclear temperature has been discussed. For the backward angle events statistical emission is the dominant process, i. e. the particles emitted into backward angles mainly come from the equilibrium decay.
