    Notes: Abstract The reactions24Mg(d,p γ) and27Al(d,α γ) have been used to study the main γ-decay modes of all bound and several unbound levels in25Mg up toE x=8 574 keV. The relevance of the data with respect to the rotational model is discussed.

    New aspects of the rotational model in25Mg (1974)
    Springer
    The European physical journal 266 (1974), S. 55-64

    Notes: Abstract Spin assignments have been made to the25Mg levels in theE x=5–6 MeV region fromγ-ray angular distributions measured in the22Ne(α, n y) reaction atE α=8.0 and 8.8 MeV and fromp-γ angular correlations measured in the24Mg(d, p γ) reaction atE d=6 MeV. Unique spin assignments ofJ=7/2, 5/2, 5/2, and 9/2 could be made to the levels atE x=5005, 5511, 5851, and 5967 keV, respectively. Ambigious assignments have been made to the levels atE x=5245, 5524, 5785, 6032 keV (J=11/2, 7/2), 5455 keVJ=13/2, 9/2), and 5738 keV (J=3/2, 5/2). The present data confirm previous assignments ofJ=1/2 to the levels atE x=5108 and 5466 keV, respectively. Lifetime estimates have been obtained, using the Doppler-shift attenuation method, for the levels atE x=5245 keV (τ=30–60 fs), 5785 keV (τ=50–100 fs), 5967 keV (τ=50–100 fs), and 5455 keV (τ〉1ps). All other levels in theE x=5–6 MeV region haveτ〈60 fs. A breakdown of theK-selection rule has been observed in theγ-decay of some high spin states, indicating a deviation from the strong coupling model.

    Lifetime measurements in25Mg (1974)
    Springer
    The European physical journal 271 (1974), S. 59-64

    Notes: Abstract The mean lives of25Mg levels have been studied using the Doppler-shift attenuation method in the24Mg(d, pγ) reaction atE d =6 MeV. Except for theE x =6873 keV level, all levels between 2 MeV excitation energy and the neutron binding energy could be investigated, yielding 11 mean lives and 30 limits thereof. A large number of multipole transition rates could be deduced and several parity assignments be made. The relevance of the data with respect to the rotational model is discussed. A serious breakdown of theK-selection rule, which has been proposed earlier for some high-spin states, is confirmed.
