Generalized gauge-space rotations in atomic nuclei: A critical insight
Chong Qi, Roberto J. Liotta, Ramon Wyss
We critically reexamine the concepts of pairing rotations and moments of inertia in gauge space extracted from experimental binding energies. Our analysis focuses on pairing correl…
Three-Body Barrier Dynamics of Double-Alpha Decay in Heavy Nuclei
Shulin Tang, Tao Wan, Yibin Qian +6
The simultaneous emission of two particles--double- decay--represents a long-predicted but unobserved mode of nuclear radioactivity. Here we formulate this process as a genu…
Model studies on the COVID-19 pandemic in Sweden
Chong Qi, Daniel Karlsson, Karl Sallmen +1
We study the increases of infections and deaths in Sweden caused by COVID-19 with several different models: Firstly an analytical susceptible-infected (SI) model and the standard s…
On the Validity of the Geiger-Nuttall Alpha-Decay Law and its Microscopic Basis
C. Qi, A. N. Andreyev, M. Huyse +3
The Geiger-Nuttall (GN) law relates the partial -decay half-life with the energy of the escaping particle and contains for every isotopic chain two experimentally determined…
Nucleon pair approximation description of the low-lying structure of Te and I
H. Jiang, Chong Qi, Y. Lei +3
The low-lying level schemes and electromagnetic transitions of Te, I, and the neighboring even-even nucleus Te, are calculated within the framework of the $…
Multistep shell model in the complex energy plane
Z. X. Xu, C. Qi, R. J. Liotta +1
We have adopted the multistep shell model in the complex energy plane to study nuclear excitations occurring in the continuum part of the spectrum. In this method one proceeds by s…
Competition of different coupling schemes in atomic nuclei
C. Qi, R. J. Liotta, R. Wyss
Shell model calculations reveal that the ground and low-lying yrast states of the nuclei Pd and Cd are mainly built upon isoscalar spin-aligned neutron-pro…
Molecular structure of highly-excited resonant states in Mg and the corresponding Be+O and C+C decays
C. Xu, C. Qi, R. J. Liotta +4
Exotic Be and C decays from high-lying resonances in Mg are analyzed in terms of a cluster model. The calculated quantities agree well with the corresponding expe…
Calculation of the spectrum of 12Li by using the multistep shell model method in the complex energy plane
Z. X. Xu, R. J. Liotta, Chong Qi +4
The unbound nucleus Li is evaluated by using the multistep shell model in the complex energy plane assuming that the spectrum is determined by the motion of three neutrons o…
Abrupt changes in alpha decay systematics as a manifestation of collective nuclear modes
Chong Qi, A. N. Andreyev, M. Huyse +3
An abrupt change in decay systematics around the N=126 neutron shell closure is discussed. It is explained as a sudden hindrance of the clustering of the nucleons that eventual…
Universal decay law in charged-particle emission and exotic cluster radioactivity
Chong Qi, Furong Xu, Roberto J. Liotta +1
A linear universal decay formula is presented starting from the microscopic mechanism of the charged-particle emission. It relates the half-lives of monopole radioactive decays wit…
