In this paper we investigate the rotational band built upon a two-quasiparticle 8− isomeric state of 252No up to spin I π = 22−. The excited states of the band were populated with the 206Pb(48Ca, 2n) fusion-evaporation reaction. An unambiguous assignment of the structure of the 8− isomer as a 7/2+[624]ν ⊗ 9/2−[734]ν configuration has been made on the basis of purely experimental data. Comparisons with triaxial self-consistent Hartree-FockBogoliubov calculations using the D1S force and breaking time-reversal as well as z-signature symmetries are performed. These predictions are in agreement with present measurements. Mean-field calculations extended to similar states in 250Fm support the interpretation of the same two-neutron quasiparticle structure as the bandhead in both N = 150 isotones.

β and γ bands in N = 88, 90, and 92 isotones investigated with a five-dimensional collective Hamiltonian based on covariant density functional theory : Vibrations, shape coexistence, and superdeformation

(American Physical Society, 2019)

A comprehensive systematic study is made for the collective β and γ bands in even-even isotopes with neutron numbers N=88 to 92 and proton numbers Z=62(Sm) to 70 (Yb). Data, including excitation energies, B(E0) and B(E2) ...
Precision mass measurements beyond ^{132}Sn: Anomalous behaviour of odd-even staggering of binding energies

Hakala, Jani; Dobaczewski, Jacek; Gorelov, Dmitry; Eronen, Tommi; Jokinen, Ari; Kankainen, Anu; Kolhinen, Veli; Kortelainen, Markus; Moore, Iain; Penttilä, Heikki; Rinta-Antila, Sami; Rissanen, Juho; Saastamoinen, Antti; Sonnenschein, Volker; Äystö, Juha (American Physical Society, 2012)

Atomic masses of the neutron-rich isotopes 121–128Cd, 129;131In, 130–135Sn, 131–136Sb, and 132–140Te have been measured with high precision (10 ppb) using the Penning-trap mass spectrometer JYFLTRAP. Among these, the ...
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al

Kostensalo, Joel; Suhonen, Jouni; Civitarese, O. (American Physical Society, 2018)

In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done ...

Background: β-delayed multiple neutron emission has been observed for some nuclei with A≤100, being the Rb100 the heaviest β2n emitter measured to date. So far, only 25P2n values have been determined for the ≈300 nuclei ...
Analysis of light neutrino exchange and short-range mechanisms in 0νββ decay

Deppisch, Frank F.; Graf, Lukas; Iachello, Francesco; Kotila, Jenni (American Physical Society (APS), 2020)

Neutrinoless double beta decay (0νββ) is a crucial test for lepton number violation. Observation of this process would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. ...
