The first reaction spectroscopy on the ground state structure of 33Mg through the measurement ofthe longitudinal momentum distribution from the one-neutron removal reaction using a C target at 898 A MeV is reported. The experiment was performed at the FRS, GSI. The distribution has a relativelynarrow width (150 ± 3 MeV/c (FWHM)) and the one-neutron removal cross-section is 74 ± 4 mb. An in-creased contribution from the 2p3/2 orbital is required to explain the observation showing its loweringcompared to existing model predictions. This provides new information regarding the configuration of 33Mg and the island of inversion.
