Introduction
Welcome to the webpage of Research Group for Reactions Involving Heavy Nuclei. Presently, group consists of 15 people.The main subjects of the groups research are: fusion-fission; quasi-fission; fission induced by surrogate reactions; neutron time-of-flight, etc. The group has strong theory support. The group peforms experiments at the JAEA tandem, and J-PARC. Apart of 'home' experimental program, members of the group are involved in close collaboration with SHIP (GSI), ISOLDE (CERN), GARIS (RIKEN), University of York, HRIBF(ORNL)...
