Research Interests
 Grouptheory approaches to nuclear structure and reactions
 Improving nuclear structure inputs for nuclear reactions
 Indirect methods for determining nuclear reaction cross sections for astrophysics and other applications
 Interplay of statistical and direct reactions, formation, and decay of compound nuclei
 Theoretical descriptions of lowenergy nuclear reactions
Jutta Escher’s background is in theoretical nuclear physics, and she has worked in lowenergy nuclear structure and reaction theory. Her current focus is developing indirect methods for determining cross sections for reactions involving unstable nuclei—such reactions play a crucial role in the quest to understand stellar evolution and the origin of the elements. They are also critical for nuclearenergy applications and for interpreting radiochemical data related to national security applications. Her goal is to achieve microscopic descriptions of the reaction mechanisms involved and to enable indirect measurements at both stablebeam and radioactive beam facilities, such as the Facility for Rare Isotope Beams.
Escher has developed grouptheoretical descriptions of nuclear structure and is now investigating avenues for using grouptheoretical approaches in nuclear reaction theory. She has (co)organized a number of scientific meetings and is the founding organizer of the international workshop series CompoundNuclear Reactions and Related Topics.
