Institute of Modern Physics, Chinese Academy of Sciences

The Institute of Modern Physics (IMP) of the Chinese Academy of Sciences was founded in l957. As of 2013, the institute had 892 staff members including 403 researchers, as well as 284 master's and doctoral students.IMP operates the Heavy Ion Research Facility in Lanzhou (HIRFL), which consists of the Sector Focusing Cyclotron

  • Highly Relativistic Bound Systems Described by a Novel Theoretical Approach

    The researchers obtain the pion and the kaon parton distribution functions (PDFs) from the overlap of the eigenstates of an effective confining and chiral Hamiltonian in the valence quark-antiquark representation suitable for low-momentum scale applications. After QCD evolution, the PDF of the pion is shown in Fig.1 which describes the probability of finding a parton (quark, gluon) carrying a (longitudinal) momentum fraction x of the pion momentum. The ratio of the up quark PDF of the kaon to that of the pion is shown in Fig. 2. We observe that our results are consistent with the experimental data as well as with other phenomenological models.Learn more

  • Important progress of mononuclear rhenium carbonyl complex in the gas phase

    Recently, the systematic study on the Group-VII Re carbonyls formed in the gas-phase chemical reactions was carried out. This work was led by the researchers from nuclear chemistry group of IMP in collaboration with the researchers from RIKEN (Japan) and PSI (Switzerland). This work provided a good foundation for future investigation on the superheavy Bh carbonyl complexes.Learn more
