The question of the sudden increase of collectivity in neutron-rich nuclei when approaching N = 40 has recently interested both experimentalists and theorists. In this paper we study the development of collectivity along the chromium and iron isotopic chains. The calculations are performed within two different perspectives, namely, the proton-neutron interacting boson model (IBM-2) and interacting shell model (ISM) and compared with the available experimental data. The onset of collectivity is studied through nuclear quantities and observables that suggest differences in the nuclear structure of Cr and Fe isotopical chains. Furthermore, a prediction for the shape transition from a spherical vibrator to γ -soft rotor with nucleus 58Cr standing at the critical point is discussed.

Effective axial-vector strength within proton-neutron deformed quasiparticle random-phase approximation

Delion, D. S.; Dumitrescu, A.; Suhonen, J. (American Physical Society, 2019)

We use the available experimental Gamow-Teller β− and β+/EC (electron-capture) decay rates between 0+ and 1+ ground states in neighboring even-even and odd-odd nuclei, combined with 2νββ half-lives, to analyze the influence ...
Effects of quasiparticle-vibration coupling on Gamow-Teller strength and β decay with the Skyrme proton-neutron finite-amplitude method

Liu, Qunqun; Engel, Jonathan; Hinohara, Nobuo; Kortelainen, Markus (American Physical Society (APS), 2024)

We adapt the proton-neutron finite-amplitude method, which in its original form is an efficient implementation of the Skyrme quasiparticle random phase approximation, to include the coupling of quasiparticles to like-particle ...
The shape of the Tz = +1 nucleus 94Pd and the role of proton-neutron interactions on the structure of its excited states

Yaneva, A.; Jazrawi, S.; Mikołajczuk, M.; Górska, M.; Regan, P.H.; Das, B.; Albers, H.M.; Alhomaidhi, S.; Arici, T.; Banerjee, A.; Benzoni, G.; Cederwall, B.; Chishti, M.M.R.; Dao, D.D.; Davinson, T.; Gargano, A.; Gerl, J.; Hall, O.; Hubbard, N.; Jolie, J.; Kojouharov, I.; Mistry, A.K.; Nowacki, F.; Polettini, M.; Rudigier, M.; Şahin, E.; Schaffner, H.; Sharma, A.; Armstrong, M.; Wollersheim, H.J.; Boutachkov, P.; Dickel, T.; Haettner, E.; Heggen, H.; Hornung Ch.; Knöbel, R.; Kostyleva, D.; Kurz, N.; Kuzminchuk, N.; Mukha, I.; Pietri, S.; Plass, W.R.; Podolyák Zs.; Scheidenberger, C.; Tanaka, Y.K.; Vesic, J.; Weick, H.; Ahmed, U.; Aktas, Ö.; Algora, A.; Appleton, C.; Benito, J.; Blazhev, A.; Bracco, A.; Bruce, A.M.; Brunet, M.; Canavan, R.; Esmaylzadeh, A.; Fraile, L.M.; Häfner, G.; Hucka, K.P.; John, P.R.; Kahl, D.; Karayonchev, V.; Kern, R.; Košir, G.; Lozeva, R.; Napiralla, P.; Nara Singh, B.S.; Page, R.; Petrache, C.M.; Pietralla, N.; Régis, J.-M.; Rösch, H.; Ruotsalainen, P.; Sanchez-Temble, V.; Sexton, L.; Shearman, R.; Si, M.; Werner, V.; Wiederhold, J.; Wimmer, K.; Witt, W.; Woods, P.; Zimba, G. (Elsevier, 2024)

Reduced transition probabilities have been extracted between excited, yrast states in the 𝑁=𝑍+2 nucleus 94Pd. The transitions of interest were observed following decays of the 𝐼𝜋=14+, 𝐸𝑥=2129-keV isomeric state, which ...
Statistical analysis of β decays and the effective value of gA in the proton-neutron quasiparticle random-phase approximation framework

Deppisch, Frank F.; Suhonen, Jouni (American Physical Society, 2016)

We perform a Markov chain Monte Carlo (MCMC) statistical analysis of a number of measured groundstate-to-ground-state single β+/electron-capture and β− decays in the nuclear mass range of A = 62–142. The corresponding ...

K.; Vencelj, M.; Yavor, M. I.; Zhao, J. (American Physical Society (APS), 2021)

Mass measurements of the nuclides 69As, 70,71Se, and 71Br, produced via fragmentation of a 124Xe primary beam at the Fragment Separator (FRS) at GSI, have been performed with the multiple-reflection time-of-flight mass ...
