    The low-lying levels in229Pa and parity doublets

    The nucleus 229 Pa was studied using the reactions 231 Pa(p,t) and 230 Th(p,2nγ). A level scheme based on particle and conversion-electron-gamma spectroscopy data is suggested.

    Investigation of224Ra in the226Ra(α, α′ 2n) reaction

    Positive and negative parity bands have been followed up to 10+ (possibly 12+) and 11− in224Ra and are compared to the corresponding bands in the isotone226Th. If a constant value of the intrinsic quadrupole mome...

    Level structure of217Rn and221Ra investigated in the alpha-decay225Th →221Ra →217Rn

    The nuclei221Ra and217Rn have been investigated in the α-decay chain225Th→221Ra →217Rn through γ-ray and conversion-electron studies. The short-lived225Th nuclei (T 1/2=8min) were produced in the226Ra(α, 5n) reac...

    In-beam spectroscopy of thek π=0− bands in230–236U

    TheK π=0− bands in even uranium nuclei were studied in the compound reactions231Pa(p, 2n)230U,230, 232Th(α,2n)232, 234U and236U(d, pn)236U. In-beamγ-rays were measured in coincidence with conversion-electrons, wh...

    Investigation of203, 205Hg with the (d, pγ) reaction — Identification of thei 13/2 neutron hole state in205Hg

    Low lying levels in203Hg and205Hg were studied with the (d, p) deuteron break-up reaction atE d=14 and 18 MeV. Gamma-rays and conversion-electrons were measured in coincidence with protons. In addition delayed sp...
