Surrogate Reactions Research at JAEA/Tokyo Tech

The research activities at JAEA and Tokyo Tech. in the development of a surrogate method based on multi-nucleon transfer reactions induced by (mainly) heavy-ion projectiles are presented. This project consists of 3 parts: the development of an apparatus to measure (1) fission cross sections and (2) neutron capture cross sections, and (3) the development of the underlying theoretical framework. Equipment has already been developed and preliminary experiments carried out to validate the methods and to provide new data. At the same time, theories to describe the surrogate reaction processes were constructed and conditions for the surrogate ratio method to derive the correct neutron-induced cross sections were investigated.
