Times Cited Count:39 Percentile:90.94(Physics, Nuclear)The neutron-rich isotope Ni was produced by multi-nucleon transfer reactions of
Zn in the Argonne National Laboratory, and an in-beam
-ray experiment were performed using the GRETINA array. The
and
levels of
Ni were observed for the first time. Those levels are regarded as large deformed states associated with proton excitation from the
orbit because they cannot be reproduced by a shell-model calculation assuming a small valence space without
. A theoretical analysis based on the Monte Carlo shell model published in 2014 indicates that those levels corresponds to a prolate deformed band. The present result demonstrates the occurrence of shape coexistence in neutron-rich Ni isotopes other than a known case of
Ni, and confirms the predictive power of the Monte Carlo shell-model calculation.

The International Fusion Materials Irradiation Facility (IFMIF) aims to provide an accelerator-based, D-Li neutron source to produce high energy neutrons at sufficient intensity and irradiation volume for DEMO reactor materials qualification. The IFMIF/EVEDA project, which is part of the Broader Approach (BA) agreement between Japan and EU, has the mission to work on the engineering design of IFMIF and to validate the main technological challenges. The prototype accelerator being developed in the IFMIF-EVEDA project consists of an injector, a RFQ accelerator, and a part of superconducting Linac. The design of the cryoplant for SRF-linac has been already completed and it will be started to install to the facility from coming September after the licensing. This article describes the cryoplant for the IFMIF/EVEDA prototype accelerator facility.
