We describe low-lying collective states in deformed even-even nuclei within a deformed quasiparticle randomphase approximation (dQRPA) by using a single-particle basis with good angular momentum. The statistical factors, accounting for the level occupancy, appear in the dQRPA in a natural way as rotation coefficients that take the intrinsic system to the laboratory system. We have used our model by performing a systematic analysis of E2 transitions from the first 2+ state to the ground state for all superfluid nuclei in the range 50 < Z 100 by using a common charge polarization parameter χ = 0.2. In spite of its similarity to the QRPA, this method is able to describe in an unified way gross features of electromagnetic transitions from vibrational to rotational nuclei.

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 ...

Comparison of Microscopic Interacting Boson Model and Quasiparticle Random Phase Approximation 0νββ Decay Nuclear Matrix Elements Kotila, Jenni (Frontiers Media SA, 2021)The fundamental nature of the neutrino is presently a subject of great interest. A way to access the absolute mass scale and the fundamental nature of the neutrino is to utilize the atomic nuclei through their rare decays, ...
Polarization corrections to single-particle energies studied within the energy-density-functional and quasiparticle random-phase approximation approaches Tarpanov, D.; Toivanen, Jussi; Dobaczewski, Jacek; Carlsson, B. G. (American Physical Society, 2014)Background: Models based on using perturbative polarization corrections and mean-field blocking approxima- tion give conflicting results for masses of odd nuclei. Purpose: We systematically investigate the polarization ...
Spin-multipole nuclear matrix elements in the pn quasiparticle random-phase approximation: Implications for β and ββ half-lives Kostensalo, Joel; Suhonen, Jouni (American Physical Society, 2017)Half-lives for 148 potentially measurable 2nd-, 3rd-, 4th-, 5th-, 6th-, and 7th-forbidden unique beta transitions are predicted. To achieve this, the ratio of the nuclear matrix elements (NMEs), calculated by the ...
