Strong γ-ray yrast cascades were observed in46,48Ti with the reactions44Ca(7Li, p2n)48Ti,27Al(24Mg, 3p)48Ti,48Ca(3He, 3n)48Ti and40Ca(12C, α2p)46Ti. In-beam γ-ray excitation functions, γ-ray angular distributions and γ-γ coincidences were performed. The following new levels were observed (Ex in keV):48Ti: 3510.0, 62+, 4565.9, 8+, 6104.7, 10+ and 6737.4 (11+, 12+);46Ti: 4643.5, (8+), 6242.0, (10+), 6514.0 (11+, 12+). All these new levels as well as the known yrast states in even-even 1f7/2 nuclei are well understood in the frame of the extreme 1f7/2)n shell model particularly the very-high-spin states.
