- Abstract
WOS: 000311537600003, High-spin states of K-40 have been populated in the fusion-evaporation reaction C-12(Si-30,np)K-40 and studied by means of gamma-ray spectroscopy techniques using one triple-cluster detector of the Advanced Gamma Tracking Array at the Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro. Several states with excitation energy up to 8 MeV and spin up to 10(-) have been discovered. These states are discussed in terms of J = 3 and T = 0 neutron-proton hole pairs. Shell-model calculations in a large model space have shown good agreement with the experimental data for most of the energy levels. The evolution of the structure of this nucleus is here studied as a function of excitation energy and angular momentum., EURONS AGATA [506065-R113]; Swedish Research Council [621-2008-4163, 621-2011-4522, 822-2005-3332, 821-2010-6024]; Japan Society for the Promotion of Science (JSPS) Kakenhi [23.01752]; Ankara University [05B4240002]; Polish Ministry of Science and Higher Education [DPN/N190/AGATA/2009, N N202 073935]; German BMBF [06K-167, 06KY205I, 06KY9136I]; Knut and Alice Wallenberg Foundation [2005.0184]; STFC (UK); MICINN, Spain; INFN, Italy [AIC-D-2011-0746]; Generalitat Valenciana, Spain [PROMETEO/2010/101]; MICINN, Spain [FPA2011-29854]; Comunidad de Madrid (Spain) [HEPHACOS S2009-ESP-1473]; Center for Advanced Studies of Warsaw University of Technology; Goran Gustafsson Foundation; Science and Technology Facilities Council [ST/G000727/1, ST/F004060/1, ST/I504959/1, ST/J000159/1, NuSTAR, ST/I504916/1, ST/J000108/1, ST/F004052/1, ST/J000094/1, ST/F004192/1, ST/F006950/1, ST/J000051/1], We thank the Swedish National Infrastructure for Computing (SNIC) and the Uppsala Multidisciplinary Center for Advanced Computational Science (UPPMAX) for the computer resources used in parts of the analysis.
