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...

  • A New Measurement of Charge-Exchange Reaction Helps Us Understand Core-Collapse Supernovae

    Some massive stars end their life as core-collapse supernovae (CCSNe), which is the most energetic and mysterious event in the universe. A large amounts of energy will be released during CCSNe and the whole galaxy can be lighted up. Decades of efforts have been devoted to understanding CCSNe while some open questions still remain. One of the important physical inputs in CCSNe simulations is the electron-capture rate.Learn more

  • Scientists Reveal Impact of New Masses of Nuclei on X-ray Bursts

    Recently, significant progress was made in understanding the impact of new masses of nuclei on the X-ray bursts by an international nuclear astrophysical team. Type I X-ray bursts are the most frequent types of thermonuclear stellar explosions in the Galaxy. Nuclear masses are key nuclear physics inputs in rp-process, and the accuracy is vital for soundly understanding the mechanism of X-ray bursts. Learn more

  • 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.
