New neutron-deficient isotopes from Kr fragmentation
B. Blank, T. Goigoux, P. Ascher +49
In an experiment with the BigRIPS separator at the RIKEN Nishina Center, the fragmentation of a Kr beam allowed the observation of new neutron-deficient isotopes at the prot…
Shape coexistence near the neutron number N=20: First identification of the E0 decay from the deformed 0^+_2 state in 30Mg
W. Schwerdtfeger, P. G. Thirolf, K. Wimmer +17
The 1789 keV level in 30Mg was identified as the first excited 0^+ state by measuring its E0 transition to the ground state. The measured small value of rho^2(E0,0^+_2 --> 0^+_1) =…
A two-neutron halo is unveiled in F
S. Bagchi, R. Kanungo, Y. K. Tanaka +44
We report the measurement of reaction cross sections () of F with a carbon target at RIKEN. The unexpectedly large and derived matter radiu…
Unexpected distribution of strength in the calcium isotopes at =30
H. L. Crawford, A. O. Macchiavelli, P. Fallon +30
The calcium isotopes have emerged as an important testing ground for new microscopically derived shell-model interactions, and a great deal of focus has been directed toward this r…
The Structure of Si and the magicity of the N=20 gap at Z=14
S. Jongile, A. Lemasson, O. Sorlin +20
The structure of Si was studied by a one-neutron knockout reaction from a Si beam at 98.5 MeV/u incident on a Be target. The prompt -rays following the de-e…
Performance of newly constructed plastic scintillator barrel in the WASA-FRS experiments and evaluation of radiation damage effects on multi-pixel photon counter
Y. K. Tanaka, R. Sekiya, K. Itahashi +70
A barrel-shaped plastic scintillation counter with Multi-Pixel Photon Counter (MPPC) readout has been developed and operated in the first WASA-FRS experimental campaign at GSI. The…
