New finite-range droplet mass model and equation-of-state parameters

P Möller, WD Myers, H Sagawa, S Yoshida - Physical Review Letters, 2012 - APS
The parameters in the macroscopic droplet part of the finite-range droplet model (FRDM) are

We describe and apply a version of the finite amplitude method for obtaining the charge-
changing nuclear response in the quasiparticle random-phase approximation. The method …

Influence of 2p-2h configurations on -decay rates

AP Severyukhin, VV Voronov, IN Borzov, NN Arsenyev… - Physical Review C, 2014 - APS
The effects of the phonon-phonon coupling on the β-decay rates of neutron-rich nuclei are
studied in a microscopic model based on Skyrme-type interactions. The approach uses a …
