  3. 3. Lifetime Measurements of Excited States in the Semi-Magic Nucleus 94Ru

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Aysegul Ertoprak; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; lifetime measurements; doppler shift attenuation method; thick target; Physics; Fysik;

    Abstract : Lifetimes of highly excited states in the semi-magic (N=50) nucleus 94Ru were deduced from an analysis of the Doppler broadened transition line shapes. Excited states in 94Ru were populated in the 58Ni(40Ca, 4p)94Ru∗ fusion-evaporation reaction at the Grand Accélérateur National d’Ions Lourds (GANIL) accelerator complex situated in Caen, France.
