The nuclear structure of neutron-rich nuclei around A ∼ 100 shows shape transitions and large deformations. Among others, these include ellipsoidal oscillation of the shape (γ-vibrations). One-phonon γ-bands are observed in numerous deformed nuclei, however, observations of two or higher-order phonon γ-bands are rare. While the even-Z nuclei have been well investigated, the spectroscopy of...
Recent predictions of reactors $\bar{\nu}$ spectra have revealed two irregularities: the Reactor Antineutrino Anomaly (RAA) and the spectral "bump" [1,2,3]. These predictions, calculated with the Huber-Muller Conversion model [4,5], have provoked several doubts about the integrity of experimental data and the accuracy of the models used. In view of this, improved measurements of nuclear data...
Conventional high-resolution techniques for $\beta$-decay spectroscopy utilize high-purity germanium detectors to measure individual $\gamma$ rays emitted after $\beta$ decay. However, this kind of measurement is affected by the Pandemonium systematic error [1], resulting in many high-energy $\gamma$ rays and a significant portion of the $\beta$ strength being missed. The Total Absorption...
Experimental data of isomerism in the neutron-rich N ≥ 126 region are important to test the predictability of shell evolution beyond the N = 126 shell closure by shell-model calculations. Moreover, the predicted properties of more exotic isotopes could affect the abundance of actinides in r-process calculations [1]. However, these information are scarcely available as it is challenging to...
The nuclear structure of doubly magic nuclei such as $^{100}$Sn and its neighboring isotopes is of significant interest due to the valuable insights it offers for testing the nuclear shell model. However, describing the nearby Cd isotopic chain poses additional challenges due to the enhanced correlations induced by two proton holes in the g9/2 orbit. In particular, $^{98}$Cd (Z=48, N=50)...
