Abstract: The α emissions in heavyion collisions at intermediate energies are studied by using isospindependent quantum molecular dynamics model. The number of α emitted is found to be strongly dependent on the isospindependent meanfield and weakly on the nucleonnucleon cross sections. The number of α emitted is easy to be measured in experiment and the above conclusion is still available no matter in neutronrich systems or in neutrondeficient systems in a wide energy region, so it can be used as an excellent probe for extracting information of the isospindependent meanfield. After several years searching, some information of the isospin asymmetry equation of state has been obtained in theoretically. We suggest to investigate the number of α emitted in neutronrich systems and the number of proton emitted in neutrondeficient systems experimentally to obtain more information of the isospindependent meanfield and the isospindependent nucleonnucleon cross section.
