Description
We propose a new measurement for the precise determination of the 2s1/2 →2p3/2 transition energy in Li-like uranium by means of resonant coherent excitation of ions in a thin Si-crystal. The goal of the proposed measurement is to determine the transition energy with an accuracy of the order ppm by a more precise determination of the ion beam energy. Also the RCE in non-channeling conditions (3D-RCE) will be tested for the same transition.
The present proposal was two times recommended by the G-PAC with A score and was scheduled for runs in 2020, 2021 and 2022. The first two schedules where canceled due to the covid19-pandemic. In 2022 the experiment was prepared for the beam time in cave a but unfortunately the accelerator could not deliver the needed beam in due time.
The GSI management proposed to consider the experiment for the beam time schedule 2023 without additional G-PAC evaluation.
