被引用回数:5 パーセンタイル:62.78(Astronomy & Astrophysics)The mirror nuclei P and S, produced via the Ne+C reaction at 33 MeV, were studied at Legnaro Laboratory using the EUCLIDES Si array coupled with the GASP Ge array. The observed B(E1) strengths of mirror E1 transitions, provide strong evidence for breaking of isospin symmetry in the A=31 mass region. The new finding are supported and explained by state-of-the-art beyond-mean-field calculations including 2- and 3-body forces. According to these findings, the breaking of isospin symmetry originate from violation of charge symmetry in the 2- and 3-body parts of the Coulomb potential.

被引用回数:2 パーセンタイル:24.58(Physics, Nuclear)Five new 2 levels and one new 3 level were established in Po. The states were populated via the Pb(C, Be) two-proton reaction experiment, performed at the JAEA Tandem in Tokai. A setup combining Ge, LaBr, and Si telescopes was used to detect in-beam -rays and ejectile residues. Two-proton configurations were assigned to all new states. All assignments are strongly supported by shell-model calculations.
