Autor: Y. Muramoto, S. Hayatsu, M. Hiyama, D. Murai, S. Kunisue

Publikováno v: Proceedings of the International Association of Hydrological Sciences, Vol 382, Pp 143-147 (2020)

In Chiba prefecture in Japan, it has been reported land subsidence for many decades. One of the causes of land subsidence is considered gas production. To reduce and control land subsidence, we applied PDCA method in a certain new development area. A

Our association plans to construct in situ formation deformation monitoring wells for shallow formation. In the pilot test, production and injection will be conducted to make the formation deform. Based on the result of the pilot test, we will invest

Single-neutron knockout from 20C and the structure of 19C

Publikováno v: Physics Letters B, Vol 769, Iss C, Pp 503-508 (2017)

The low-lying unbound level structure of the halo nucleus 19C has been investigated using single-neutron knockout from 20C on a carbon target at 280 MeV/nucleon. The invariant mass spectrum, derived from the momenta of the forward going beam velocity

Interaction cross section study of the two-neutron halo nucleus 22C

Publikováno v: Physics Letters B, Vol 761, Iss C, Pp 412-418 (2016)

The interaction cross sections (σI) of the very neutron-rich carbon isotopes 19C, 20C and 22C have been measured on a carbon target at 307, 280, and 235 MeV/nucleon, respectively. A σI of 1.280±0.023 b was obtained for 22C, significantly larger th
