Abstract

Lifetimes of excited nuclear states were determined in Ti-44 using the recoil distance Doppler-shift technique and the Doppler-shift attenuation method. Results from the K-pi = 3(-) band confirm isospin-symmetry breaking for the 3(1)(-) -> 2(1)(+) E1 transition. The lifetime of the 4(1)(-) state differs considerably from the previously known value. Good agreement is found for the 4(1)(+) and 6(1)(+) level lifetimes with respect to previous values. The experimental values are compared with large-scale shell-model calculations employing established interactions in the 0f1p shell, as well as a modern effective Hamiltonian including multiparticle multihole cross-shell configurations. Extended configuration spaces of this shell-model calculation allow for a detailed comparison with newly determined negative-parity states.
