ABSTRACT
The experimental knowledge of the 2961Cu32 and 3061Zn31 nuclei has been largely extended via the joint results from three experiments. The fusion-evaporation reaction used a 36Ar beam and a 28Si target foil to produce the two nuclei via the evaporation of either three protons (61Cu) or two protons and a neutron (61Zn). The experimental set-ups comprised the Ge-array GAMMASPHERE as well as neutron and charged-particle detectors placed around the target position. The resulting level schemes include around ten rotational superdeformed structures in each isotope. Most of them are linked to normally deformed states and in many cases spins and parities of the low-lying states in each structure have been determined. The collective structures are compared with results from configuration dependent Cranked Nilsson-Strutinsky calculations. The different structures are in general well understood from the calculation but the results do also suggest modifications of the standard Nilsson parameters in the mass A∼60 region.

    It is shown that the list of unusual mesons that are planned to be studied in photoproduction reactions can be supplemented with I[sup G] (J[sup PC]) = 2[sup +] (2[sup ++]) exotic states X[sup ±](1600), which are natural to seek as manifestations of the ρ[sub ±]ρ[sup 0] decay...

    We investigated the evolution of experimental two-neutron separation energies (S2n) along the isotopic chains for the even-even nuclei. In order to enhance the sensitivity of our search, differential variation of the S2n has been investigated. The emphasis is on finding nonmonotonic behaviors...

    There has been significant progress in the ab initio approaches to the structure of light nuclei. One such method is the ab initio no-core shell model (NCSM). Starting from realistic two- and three-nucleon interactions this method can predict low-lying levels in p-shell nuclei. In this...

    By comparing the Q -values for the 46Ti ( 3He , t46V and 47Ti ( 3He , t47V reactions to the isobaric analogue states the Q -value for the superallowed Fermi decay of 46V has been determined as QEC( ^46V ) = (7052.11±0.27) keV. The result is compatible with the values from two recent direct...

    The theory of Quantum Chromo Dynamics (QCD) reproduces the strong interaction at distances much shorter than the size of the nucleon. At larger distance scales, the generation of hadron masses and confinement cannot yet be derived from first principles on basis of QCD. The PANDA experiment at...
