Abstract An extensive shell-model calculation has been performed on fivefp-shell nuclei in the mass regionA = 48–52. The model space, which includes 1p-1h excitations, reproduces the experimental spectra very well except for the 0 2 + state in50Ti. It is demonstrated that the 0 2 + state can be reproduced by a model space which also includes 2p-2h excitations. Strong neutronp-h components in the wave functions of states in 22 50 Ti28 are found despite the closure of the neutron f7/2 orbit. Magnetic transitions in50Ti are discussed, and in contrast to the 1p-1h results a sufficiently large quenching ofB(M1) strengths in the 2p-2h model space is found. Effects of 2p-2h admixtures onM 5 transition strengths are discussed as well.
