Physicists Measure Mass Numbers of Nihonium and Moscovium

Left: average of known decay properties assigned to 288Mc and its daughters. Right: details of decay chains detected at the FIONA focal plane. Unobserved decays within each decay chain are indicated as ‘unobserved’ and are assumed to have been emitted out of the open end of the detector array. The x position of decays observed in the focal-plane detector is also given. Image credit: Gates et al, doi: 10.1103/PhysRevLett.121.222501.

Physicists using the FIONA (For the Identification Of Nuclide A) device at the Department of Energy’s Lawrence Berkeley National Laboratory’s 88-inch Cyclotron have performed the first direct measurements of the mass numbers for the nuclei of nihonium (Nh, element 113) and moscovium (Mc, element 115). Left: average of known decay properties assigned to 288Mc and its daughters. Right: details of decay chains detected at the FIONA focal plane. Unobserved...

A chemically termolecular reaction is a reaction where three different molecules (e.g. H, O2, H) each participate in the breaking and forming of chemical bonds. The reaction is mediated by an ephemeral collision complex (HO2**) formed from the collision of two molecules (H, O2) which then reacts upon colliding with a third molecule (H).
