Towards a Better Understanding of the Short-range Repulsive Nuclear Force
In a new study, researchers provide an experimental estimate of the short-range repulsive nuclear force strength based on a high-statistics measurement of the differential cross-section for Σ+p scattering.
Towards Radionuclide Cancer Therapy with High Purity 177Lu from Enriched 176Yb Samples

How Good is the Transition-State Theory?
For the first time, the main assumption of the transition-state theory for the decay of complex quantum systems across a potential barrier was realized using a microscopic many-body Hamiltonian.

Estimating Beta Decay Rates Better for Exotic Nuclei
Physicists from Japan demonstrate an improved estimation of the beta decay rate in heavy nuclei by considering next-to-leading-order approximation for the electron wave function distorted by the Coulomb potential.
