VADER : A novel decay station for actinide spectroscopy
Abstract
A research programme focused on the study of the nuclear structure of actinide isotopes has recently been
implemented at the IGISOL facility, University of Jyväskylä. Within this scope, a new decay station named
VADER (Versatile Actinides DEcay spectRoscopy setup) has been developed and commissioned. The system
consists of a compact array of silicon detectors, a liquid-nitrogen-cooled silicon lithium (Si(Li)) detector and
three broad energy germanium detectors (BEGe), placed around a thin implantation carbon foil. The combined
use of different detectors allows the measurement of 𝛼 particles, conversion electrons and de-excitation 𝛾 rays in coincidence, enabling a full reconstruction of nuclear decay schemes. The measurement of basic nuclear decay observables provides a picture of the nuclear shell evolution in neutron-deficient actinides, and highlights the possible emergence of reflection-asymmetric shapes in the region.
