[en] Magnetic dipole excitations in N = 28 isotones ⁴⁸Ca, ⁵⁰Ti, ⁵²Cr and ⁵⁴Fe are studied in terms of shell model which includes configurations with one- and two-particle excitations from fsub(7/2) to psub(3/2), psub(1/2) and fsub(5/2) shell orbits. Distributions of the strength observed in (e, e') and (p, p') experiments are well reproduced. Total strength reduces by about 25% due to the mixing in the 0⁺ ground state, but the calculated strengths are yet 2-3 times greater than the experimental values. Contributions arising from proton excitation and the orbital magnetization are also discussed. (orig.)
