The Gamow-Teller transition (G-T) strengths are important for understanding nucleosynthesis in stars. The transition strength not only from a ground state but also from an excited state become important in some cases. Charge exchange reactions provide information of G-T strength even for transitions to excited states. However such studies had been done only at around stable nuclei. Here we...

Evolution of nuclear structure of Nitrogen isotopes (Z=7) and N=7 isotones with increasing imbalance between protons and neutrons has been a focus of intense scrutiny since the discovery of parity inversion in 11-Be. Yet, the level structure of the most exotic nuclear systems with 7 neutrons or protons (such as 9-He, 10-Li, 10-N) remain uncertain and presents a major challenge both...

Direct observation of neutron-proton (np) correlations and 3N-froce in nuclei is the long-sought goal in nuclear physics. Two-nucleon knockout reactions offer a powerful tool as the reaction cross section is a direct probe of nucleon correlations. The experimental data of 12C on a carbon target reveal that the inclusive cross sections of residues from np removal channel (10B) is approximately...

Nuclear correlations involved in neutron-rich nuclei, up to the drip line, play essential roles in the understanding and modeling of neutron captures in the r-process nucleosynthesis as well as in the understanding of phenomena linked to the neutron star superfluidity. They are also interesting in view of generalizing the Ikeda conjecture, commonly applied to alpha clusters, to dineutron...

The nuclear magic numbers, as we know in stable nuclei, consist of two different series of numbers. The first series – 2, 8, 20 – is attributed to the harmonic oscillator potential, while the second one – 28, 50, 82, and 126 – is due to the spin-orbit interactions. The spin-orbit interactions are known to be significant and responsible for the large (spin-orbit) splitting of the...

The LSU-FSU Array for Nuclear Astrophysics and Structure with Exotic Nuclei (ANASEN) has been developed, in part, for the direct measurement of (α,p) reactions with radioactive beams. It is currently installed at the John D. Fox Superconducting Accelerator Laboratory at FSU. The ANASEN detector consists of position-sensitive proportional counter aligned with the beam axis surrounded by a...

The observation of a large permanent electric dipole moment (EDM) would represent a clear signal of CP violation from new physics outside the Standard Model. The 199Hg isotope currently provides the most stringent limit on an atomic EDM, which is converted to a limit on the nuclear EDM via a calculation of the Schiff moment. To do this knowledge of the nuclear structure of 199Hg is required....

According to the Independent Particle Model (IPM) single-particle (SP) states are fully occupied up to the Fermi energy with spectroscopic factors (SF) of one. However, it is well known from electron-induced proton knockout that the SP strength is reduced to about 60-70% for stable nuclei, which has been attributed to the presence of short- and long-range correlations[1]. This finding has been...
