Amazing stuff!
"... They have developed a new analysis method using a pulsed laser, based on an Optical Parametric Oscillator (OPO). This laser technology can achieve wavelengths and colours that conventional laser systems struggle to produce with sufficient intensity and wavelength precision.
The laser pulses are directed at the atoms, revealing small changes in energy in the wavelengths that are absorbed. ...
The results of the study can be used to refine theoretical models of atoms and atomic nuclei, making it easier to identify new possible elements and isotopes in future experiments. ..."
New laser method gives insight into radioactive atomic nuclei (original news release) "By directing pulses of laser light at atoms, researchers can study how radioactive elements decay in a matter of seconds. The method is described in a new thesis from the University of Gothenburg, which shows that the atomic nuclei of the elements neptunium and fermium are shaped like rugby balls."

Shapes of an atomic nucleus. The nucleus is always prolate-shaped for fermium-255, but it can vary, for the same element, depending on how many neutrons the nucleus has.
