Times Cited Count：2 Percentile：21.66(Physics, Multidisciplinary)Intensive neutron sources using deuteron accelerators have been proposed for not only science and engineering fields but also medical applications. For the engineering design of such facilities, accurate and comprehensive nuclear data of deuteron-induced reactions are indispensable. However, it is difficult to meet the requirement by employing experimental data alone. Thus, theoretical model calculations play a key role in completing the necessary nuclear data by interpolation and extrapolation of experimental data. Under the above situations, we have been developing a code system dedicated for deuteron-induced reactions, called DEURACS. In the present work, calculations using DEURACS are compared with available experimental data and validation of the present modelling in DEURACS is discussed. Moreover, the importance of consideration of the breakup processes for accurate prediction of deuteron-induced reactions is also presented.

meson in nuclear matter. I will particularly focus on the question of how the modification of the meson spectral function in nuclear matter influences the experimentally observed di-lepton spectrum.

Nevertheless, it is known that their characteristics can be well described and understood by the few-body picture. One of such pictures is the single-particle motion of a nucleon in a mean-field potential made by all nucleons. Another one is the clustering phenomenon, 
clustering for example. One of the powerful probes for such states of a nucleus is the nucleon and cluster knockout reactions. In this paper, I overview how these states can be probed by the knockout reaction and discuss the present status and the future perspectives of this research field.

reaction at 1.7 GeV/c at the K1.8 beam line. The binding energy and decay width of the bound state can be obtained in the missing mass measurement with a good energy resolution of 2 MeV/c
. A range counter array (RCA) was constructed to detect the two high-momentum protons from the decay and to reduce the background such as quasi-free hyperon production. Recently, we have carried out a pilot run in June, 2012. The missing-mass spectrum has been obtained for the first time.
