Abstract
Low spin states in the self-conjugate even-even nucleus 48-Cr were investigated using the MINIBALL gamma-ray spectrometer. At the FN tandem accelerator in Cologne the 46-Ti(3-He,n) reaction was used for the measurement of gamma-gamma coincidences for an excitation function from 7 to 12 MeV beam energy. 17 excited states were observed, nine for the first time by means of gamma-ray spectroscopy, and new spin assignments were made. No excited states apart from the ground band were observed below 3.4 MeV.
