While Gosia is the obvious tool for planning low-energy Coulomb excitation experiments, the [[Rachel,_a_GUI_for_Gosia | GUI]] for Gosia can offer much greater speed and automation in the planning process, including predicting the measurable count rate and estimating the expected errors in the planned experiment.
