Institute of Modern Physics, Chinese Academy of Sciences

The Institute of Modern Physics ( IMP ) of the Chinese Academy of Sciences was founded in l957. After a half century of development, IMP has become the most important research center for heavy ion sciences in China. We have established active and fruitful collaboration with more than 40 institutions worldwide. IMP operates the Heavy I...

  • Researchers Prove Tensor Force Invalid in Skyrme Density Functionals

    The tensor force is a hot topic in nuclear physics, which affects the shell evolution. Based on the derived tensor force in momentum space via partial-wave expansion, researchers demonstrated such a tensor force invalid, and hence the widely employed tensor force of the Skyrme interactions invalid. Researchers then proposed a new scheme and accordingly built two new Skyrme interactions—IMP1 and IMP2. The shell evolution in Sn isotopes and N = 82 isotones can be well reproduced by IMP2.

  • Isotope Laboratory of Gansu Province Established

    The Isotope Laboratory of Gansu Province, which centers on isotopes and related technologies, was unveiled on January 20th and officially established. The laboratory is operated and managed by IMP. According to the prediction of scientists, there are more than 8000 isotopes and so far about 3200 kinds have been found.Learn more

  • Scientists Reveal Enzymatic Hydrolysis Process of Alkali Pretreated Straw

    Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences have made progress in the study of enzymatic hydrolysis process of alkali pretreated straw lately. The research provides insight into the structural changes and visualization of the hydrolysis process. These findings will help to design plant cell structures and plant tissues at the organization level, and reduce the natural recalcitrance of lignocellulose, thereby enhancing the overall biomass conversion efficiency.
