Quantum mechanical calculations of atomic systems comprise a suite of computational methods that rigorously apply the principles of quantum mechanics to determine a range of atomic properties. These ...

Researchers developed a method to accurately calculate atomic forces for elements with high atomic numbers with quantum Monte Carlo simulations Ishikawa, Japan-- Atomic forces are primarily ...

Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...

High-precision measurements of the mass of the deuteron, the nucleus of heavy hydrogen, provide new insights into the reliability of fundamental quantities in atomic and nuclear physics. This is ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

For the first time those little numbers that appear beneath some of the commonest elements in the periodic table boxes are about to change from a single value to an interval of numbers An ...

A schematic diagram of proton and neutron distributions for mirror nuclei argon-31 and aluminum-31. Left side is the weakly bound proton-rich nucleus argon-31, which is predicted to exhibit a ...
