    Note on stellar26Al production via the25Mg(p, γ) process (1985)

    The European physical journal 320 (1985), S. 693-694

    Notes: Abstract Resonance energies and widths of four resonances in the reaction25Mg(p,γ)26Al were measured with the high resolution proton beam of the new 500 kV accelerator IONAS. The previously given large width of the 389 keV resonance, Γ= 460±70 eV. (1), used in the interpretation of stellar26A1 production was shown to be incorrect and probably caused by target oxidation effects and insufficient energy resolution of the beam. The new value is Γ〈4 eV.

    Rotational bands in73Br: The disappearance of shape coexistence in72Se (1985)
    Springer
    The European physical journal 322 (1985), S. 171-172

    Topics: Physics
    Notes: Abstract By means of the reaction40Ca (36Ar, 3p), the band structure of73Br connected with the g9/2 single-particle proton orbit has been investigated up to Iπ=33/2+. In contrast to the core spectrum in72Se, which is dominated by the coexistance of different shapes, the nucleus73Br features rotational bands with slowly increasing moments of inertia. Their deformation β2=0.40(2) has been deduced from recoil distanc lifetime measurements.

    Notes: Abstract High spin states in85Y have been excited in the reaction72Ge(16O,p2n) at 48–60 MeV beam energy. From measurements ofnγ andγγ coincidences, excitation functions and angular distributions, the high spin spectrum of85Y has been established up to 5.4 MeV excitation energy and spinI≦29/2. Lifetimes or limits of lifetimes have been determined for 14 levels via the recoil distance and Doppler shift attenuation method. Theg 9/2 decoupled proton band is found to backbend atI π=17/2+ as also seen in the reduction of the 17/2+→13/2+ and 21/2+→17/2+ E2 transition strengths. The lowest (3qp) positive parity band has predominantly aν 2 g 9/2×πg 9/2 structure. The observed negative parity yrast states in the spin range 15/2−≦I≦29/2− are most probably of (g 9/2)2 ×(f 5/2,p 1/2) (3qp) nature as suggested by a comparison of the84Sr and85Y level structures and electromagnetic transition strengths.
