Radiative strength functions from the energy-localized Brink-Axel hypothesis
Oliver C. Gorton, Konstantinos Kravvaris, Jutta E. Escher +1
Radiative strength functions (RSFs) model the bulk electromagnetic response of highly-excited nuclei and are critical inputs for statistical reaction codes. In this paper, we prese…
Centroids of nuclear shell-model Hamiltonians, with optimization of energy-based truncation schemes
Calvin W. Johnson, Austin Keller
The configuration-interaction shell model is an effective and widely-used approach to the nuclear many-body problem, whose main drawback is the exponential growth of the basis dime…
RHODIUM: A post-processor for BIGSTICK configuration-interaction wave functions
Calvin W. Johnson
RHODIUM is a postprocessing code for nuclear structure physics. It can be used to compute density matrices, spectroscopic amplitudes, and other information, from wave function and…
Pairing Strength and Quadrupole-Soft Tin Isotopes
Le-Anh Nguyen, Minh-Loc Bui, Panagiota Papakonstantinou +2
Background: Understanding the experimental values for Sn isotopes around Sn has been a significant challenge in nuclear structure studies for over a decade. Both ex…
Radial excitations and their potential impact on Fermi -decay rates
L. Xayavong, Y. Lim, N. A. Smirnova +1
We investigate the contribution of radial excitations to Fermi -decay matrix element. To this end, exact no-core shell model calculations are performed for the mirror deca…
Scattering phase shifts from overlap relations in the -matrix method
Calvin W. Johnson, Bui Minh Loc, Austin Keller +1
The scattering problem can be implemented in a square-integrable basis via the so-called -matrix method. While methods to compute the phase shift in the -matrix approach are…
