Abstract:	Levels of ⁴⁸Sc up to 3.33 MeV excitation were studied by the reaction ⁴⁸Ca(p,nγ)⁴⁸Sc employing a variety of experimental techniques. A level scheme of ⁴⁸Sc comprising 29 excited states and 54 transitions were determined from the measurements of γ-γ coincidences and γ-ray excitation functions. Within the framework of the statistical compound nucleus model spins and parities of the ⁴⁸Sc levels were assigned from the angular distributions and linear polarizations of the de-excitation γ-rays as well as the excitation functions of the residual levels. From the present experimental results and other available data we tentatively identified some of the levels of the ( $1 f_{72}^{9}$ , $1 d_{32}^{?1})$ , ( $1 f_{72}^{9}, 2 s_{12}^{?1}$ ), ( $1 f_{72}^{7}, 2 p_{32}$ ) and ( $1 f_{72}^{7}, 1 f_{52}$ ) configurations in addition to the well-known ( $π f_{72}, v f_{72}^{?1}$ ) multiplet.
