High-temperature Tl decay clarifies Pb dating in early Solar System
G. Leckenby, R. S. Sidhu, R. J. Chen +56
Radioactive nuclei with lifetimes on the order of millions of years can reveal the formation history of the Sun and active nucleosynthesis occurring at the time and place of its bi…
Feasibility of the observation of mesic nuclei in the semi-exclusive C() reaction
Natsumi Ikeno, Yuko Higashi, Hiroyuki Fujioka +7
We study theoretically the feasibility of the semi-exclusive C() reaction for the observation of mesic nuclei using the microscopic transport model JAM.…
Mean range bunching of exotic nuclei produced by in-flight fragmentation and fission -- Stopped-beam experiments with increased efficiency
Timo Dickel, Christine Hornung, Daler Amanbayev +24
The novel technique of mean range bunching has been developed and applied at the projectile fragment separator FRS at GSI in four experiments of the FAIR phase-0 experimental progr…
Studying Gamow-Teller transitions and the assignment of isomeric and ground states at
Ali Mollaebrahimi, Christine Hornung, Timo Dickel +50
Direct mass measurements of neutron-deficient nuclides around the shell closure below Sn were performed at the FRS Ion Catcher (FRS-IC) at GSI, Germany. The nuclei w…
Chiral symmetry restoration at high matter density observed in pionic atoms
Takahiro Nishi, Kenta Itahashi, DeukSoon Ahn +45
Modern theories of physics tell that the vacuum is not an empty space. Hidden in the vacuum is a structure of anti-quarks and quarks . The and pair has t…
A Novel Method for the Measurement of Half-Lives and Decay Branching Ratios of Exotic Nuclei
Ivan Miskun, Timo Dickel, Israel Mardor +28
A novel method for simultaneous measurement of masses, Q-values, isomer excitation energies, half-lives and decay branching ratios of exotic nuclei has been demonstrated. The metho…
High-resolution, accurate MR-TOF-MS for short-lived, exotic nuclei of few events in their ground and low-lying isomeric states
S. Ayet, C. Hornung, J. Ebert +37
Mass measurements of fission and projectile fragments, produced via U and Xe primary beams, have been performed with the multiple-reflection time-of-flight mass spe…
Spectroscopy of pionic atoms in reaction and angular dependence of the formation cross sections
T. Nishi, K. Itahashi, G. P. A. Berg +36
We observed the atomic and states of bound to nuclei as distinct peak structures in the missing mass spectra of the ${}^{122}{\rm Sn}(d,{}^3{\rm…
Missing-mass spectroscopy of the reaction near the -meson production threshold
Y. K. Tanaka, K. Itahashi, H. Fujioka +51
Excitation-energy spectra of C nuclei near the -meson production threshold have been measured by missing-mass spectroscopy using the C(,) reaction. A…
Search for η'(958)-nucleus bound states by (p,d) reaction at GSI and FAIR
H. Fujioka, Y. Ayyad, J. Benlliure +51
The mass of the η' meson is theoretically expected to be reduced at finite density, which indicates the existence of η'-nucleus bound states. To investigate these states, we perfor…
Spectroscopy of eta' mesic nuclei with (p,d) reaction
Yoshiki K. Tanaka, Stefan Friedrich, Hiroyuki Fujioka +15
We are going to perform an inclusive spectroscopy experiment of eta' mesic nuclei with the 12C(p,d) reaction to study in-medium properties of the eta' meson. In nuclear medium, the…
Spectroscopy of eta'-nucleus bound states at GSI-SIS
Hiroyuki Fujioka, Kenta Itahashi, Hans Geissel +14
The eta' meson mass may be reduced due to partial restoration of chiral symmetry. If this is the case, an eta'-nucleus system may form a nuclear bound state. We plan to carry out a…
Feasibility Study of Observing eta' Mesic Nuclei with (p,d) Reaction
Kenta Itahashi, Hiroyuki Fujioka, Hans Geissel +13
A novel method is proposed to measure eta'(958) meson bound states in 11C nuclei by missing mass spectroscopy of the 12C(p,d) reaction near the eta' production threshold. It is sho…
