TL;DR: The Advanced GAmma Tracking Array (AGATA) has been installed at the GANIL facility, Caen-France as discussed by the authors, where it has been designed to couple AGATA with a magnetic spectrometer, charged-particle and neutron detectors, scintillators for the detection of high energy γ rays and other devices such as a plunger to measure nuclear lifetimes.

TL;DR: In this article, the PSDPF interaction has been used to assign spin-parity assignment to excited states with intermediate and high spins in two nuclei, and the level schemes of both nuclei have been considerably extended.

Lifetime measurements in Ti 44
K. Arnswald,P. Reiter,A. Blazhev,Thomas Braunroth,A. Dewald,M. Droste,C. Fransen,A. Goldkuhle,R. Hetzenegger,R. Hirsch,E. Hoemann,L. Kaya,L. Lewandowski,C. Müller-Gatermann,P. Petkov,D. Rosiak,M. Seidlitz,B. Siebeck,A. Vogt,D. Werner,K. Wolf,K. O. Zell +21 more
TL;DR: In this article, the lifetime of excited nuclear states was determined using the recoil distance Doppler-shift technique and the attenuation method, and the experimental results were 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.
