Finite-spectrum Lorentz integral transform calculation of the He photoabsorption cross section in the no-core shell model
P. Yin, H. T. Zhao, C. Y. Zhai +11
We develop and validate a finite-spectrum implementation of the Lorentz integral transform (LIT) within the \textit{ab initio} no-core shell model (NCSM) for calculating the photoa…
A modern Fortran library for SU(3) coupling and recoupling coefficients
Jakub Herko, Mark A. Caprio, Anna E. McCoy +1
The group has applications in several branches of physics. Many of these applications depend on availability of coupling and recoupling coefficien…
Robust ab initio predictions for dimensionless ratios of E2 and radius observables. II. Estimation of E2 transition strengths by calibration to the charge radius
Mark A. Caprio, Patrick J. Fasano, Pieter Maris
Converged results for E2 observables are notoriously challenging to obtain in ab initio no-core configuration interaction (NCCI) approaches. Matrix elements of the E2 operator are…
