Using laser spectroscopy, the team were able to measure the nuclear radius of several isotopes of nobelium and fermium.

Unlike lighter regions of the nuclear chart, where upward kinks are observed crossing shell closures, the trend across a key neutron number is shown to be smooth. This indicates that nuclear shell effects due to a few nucleons have a reduced influence as the so-called superheavy elements are approached, and the nuclei behave more like a deformed liquid drop.

Researchers from the University of Liverpool’s Department of Physics, Professor Bradley Cheal and Dr. Charlie Devlin, contributed to the nobelium experimental activities of the study.

Scientists have created a compact spectral singlet lens that turns standard cameras into hyperspectral ones, reducing system size and complexity. This breakthrough could expand hyperspectral imaging into portable applications, with future improvements underway.

The information we gather shapes our understanding and perspectives of the world. For centuries, optics has sought to interpret the multidimensional data around us through the “toolbox” of light. In the 17th century, Sir Isaac Newton introduced the lens imaging formula and conducted his famous color spectrum experiment, laying foundational insights in the field.

Since then, lenses and spectrometers have been extensively studied as essential optical components for capturing information. Cascading these two components can allow us to acquire more information – both spatial and spectral data. However, such a configuration leads to tradeoffs among device footprint, spectral resolution, and imaging quality, impeding portability and miniaturization of hyperspectral cameras.
