We have developed the KEK Isotope Separation System (KISS) at RIKEN to study the nuclear structure of the nuclei in the vicinity of neutron magic number N=126 from the astrophysical perspective. These neutron-rich nuclei have been produced by using multinucleon transfer (MNT) reactions with combinations of the low-energy 126<\/sup>Xe beam and the production targets of W, Ir, and Pt. At the KISS facility, radioisotopes are ionized by applying in-gas-cell laser ionization technique. In this process, we can perform laser ionization spectroscopy of the refractory elements with the atomic number Z=70\u201378 such as Hf, Ta, W, Re, Os, Ir, and Pt, which cannot be performed in other facilities. Laser spectroscopy can effectively investigate nuclear structure through the measured magnetic moments, isotope shifts (IS) \u0394\u03bd, changes in the mean-square charge radii \u03b4<r2<\/sup>>, and quadrupole deformation parameters |<\u03b22<\/sup>>|1\/2<\/sup>. We have studied the ionization schemes of these elements through offline tests and performed in-gas-cell laser ionization spectroscopy of these refractory neutron-rich nuclei produced at KISS.<\/p>\n","protected":false},"excerpt":{"rendered":"In-gas-cell laser ionization spectroscopy at KISS Yoshikazu Hirayama, Momo Mukai, Yutaka Watanabe, Peter Schury, Toshitaka Niwase, Hyunsuk Choi, Takashi Hashimoto, Shun Iimura, SunChan Jeong, Hiroari Miyatake, JunYoung Moon, Hitoshi Nakada, Michihiro Oyaizu, Marco Rosenbusch, Aiko Takamine, Minori Tajima, Akihiro Taniguchi,...<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","enabled":false}}},"categories":[3],"tags":[324,156,294,296,325],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p6YIb0-6Z","jetpack-related-posts":[{"id":249,"url":"https:\/\/magneticmoments.info\/wp\/?p=249","url_meta":{"origin":433,"position":0},"title":"[paper] In-gas-cell laser spectroscopy of the magnetic dipole moment of the N\u2248126 isotope 199Pt","date":"Jul 11, 2017","format":false,"excerpt":"In-gas-cell laser spectroscopy of the magnetic dipole moment of the N\u2248126 isotope 199Pt Y.
