Studies) ; Kvasil, J (Charles U.) ; Fogelberg, B (Uppsala U.) ; Gulda, K (Warsaw, Inst. Nucl. Studies ; Warsaw U.) ; Aas, A J (Oslo U.) ; Borge, M J G (CSIC, Madrid) ; Grant, I S (Manchester U.) ; Hagebø, E (Oslo U.) et al.
We have applied the fast timing $ \beta\gamma\gamma (t)$ technique to remeasure lifetimes of selected states in$^{223}$Ra populated in the $ \beta^{-}$ decay of$^{223}$Fr. $ T_{1/2}=587(12)$ ps and 210(13)ps have been obtained for the $ 3/2^{-}$ and $ 5/2^{-}$ states at 50.1 and 79.7 keV, that are more accurate than the previous values of 630(70)ps and 166(55)ps, respectively.

Lifetimes of excited states in $^{229}$Th, populated in the $\beta$-decay of $^{229}$Ac, have been measured using the advanced time-delayed $\beta\gamma\gamma$(t)-method. Half-lives of 14 states have been determined including 11 of them for the first time. [...]

Neutron resonance study of a delayed neutron emitter, /sup 87/Kr
/ Fogelberg, B ; Harvey, J A ; Macklin, R L ; Raman, S ; Stelson, P H
The unbound levels in /sup 87/Kr have been studied as neutron resonances up to 400 keV neutron energy at the ORELA linear electron accelerator. The observed p-wave resonances, with I/sup pi /=1/2/sup - / and 3/2/sup -/ can also be populated in the beta -decay of the 3/2 /sup -/ ground state of /sup 87/Br. [...]

Decay properties of /sup 81/Ga and /sup 81/Ge and observation of abnormal energy shift in the p/sub 1/2/ state
/ Hoff, P ; Aleklett, K ; Fogelberg, B ; Lund, E ; Rudstam, G
/sup 81/Ga is efficiently produced in the isotope separator on-line facility OSIRIS at Studsvik, utilizing thermal fission of /sup 235/U. The germanium isobars are studied as daughter products. [...]
