Number of α Emitted as a Probe of the Isospin Dependent Mean field

    Graphical Abstract
    • Abstract
  • The α emissions in heavyion collisions at intermediate energies are studied by using isospindependent quantum molecular dynamics model. The number of α emitted is found to be strongly dependent on the isospindependent meanfield and weakly on the nucleonnucleon cross sections. The number of α emitted is easy to be measured in experiment and the above conclusion is still available no matter in neutronrich systems or in neutrondeficient systems in a wide energy region, so it can be used as an excellent probe for extracting information of the isospindependent meanfield. 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 neutronrich systems and the number of proton emitted in neutrondeficient systems experimentally to obtain more information of the isospindependent meanfield and the isospindependent nucleonnucleon cross section.
