The research group carries out experimental studies on the synthesis and structure of neutron deficient nuclei, using the facilities of gas-filled recoil separator, SHANS (Spectrometer for Heavy Atoms and Nuclear Structure) and HPGe gamma-ray detector array at HIRFL, as well as other facilities around the world. Meanwhile, a novel device, MRTOF (multi-reflection time-of-flight) mass spectrometer for precise mass measurement of short-lived nuclei is under construction. For the coming HIAF facility, the laboratory is responsible for the development of facilities of new gas-filled recoil separator and multi-nucleon transfer reaction spectrometer.
Currently, 24 employees, 2 foreign postdoctoral fellows and 10 graduate students are working at the laboratory.
New isotope 214U has been observed by scientisits from our group and collaborators and published in Phys. Rev. Lett. 126 (2021) 152502 as an Editors’ Suggestion on April 14. It has revealed for the first time the abnormal enhancement of α-particle clustering in uranium isotopes. This result has also been reported by Physics.
New very short-lived isotope 222Np has been observed by scientisits from our group and collaborators and published in Phys. Rev. Lett. 125 (2020) 032502. This has been reported not only by medias from China, but also from abroad. The following are links:
