New isomeric states in /sup 218/Fr and /sup 214/At / Ewan, G T ; Hagberg, E ; Jonson, B ; Mattsson, S ; Tidemand-Petersson, P
Alpha spectroscopic data from the decay chain /sup 218/Fr to /sup 214 /At to /sup 210/Bi have been obtained. Previously unobserved isomeric states were found in both /sup 218/Fr and /sup 214/At. [...]

Excited states in the doubly closed shell nucleus $^{132}_{50}Sn_{82}$ / Bjørnstad, T ; Blomqvist, J ; Ewan, G T ; Jonson, B ; Kawade, K ; Kérek, A ; Mattsson, S ; Sistemich, K /ISOLDE Collaboration
New excited states in the nucleus /sup 1/ /sup 32/Sn have been identified from gamma gamma coincidence measurements. Strong beta feeding to a state at 7.210 keV was established. [...]

Evidence for sudden of rotational structure in heavy Sr nuclides / Azuma, R E ; Borchert, G L ; Carraz, L C ; Hansen, P G ; Jonson, B ; Mattsson, S ; Nielsen, O B ; Nyman, G H ; Ravn, H L
The authors give evidence for rotational 2/sup +/ and 4/sup +/ levels in /sup 100/Sr. The nuclide /sub 37//sup 100/Rb with half-life of 55 ms was produced by mass separation at the ISOLDE Facility by bombarding a uranium carbide target with 600 MeV protons. [...]

The N=Z nuclide $^{74}Rb$ with $T, I^{\pi} =1, 0^{+}$ / D'Auria, J M ; Carraz, L C ; Hansen, P G ; Jonson, B ; Mattsson, S ; Ravn, H L ; Skarestad, M ; Westgaard, L
Improved experimental techniques have permitted the observation of the new nuclide /sup 74/Rb with a half-life of 64.9+or-0.5 ms, which represents the heaviest self-conjugate nuclear detected until now. The absence of a long-lived isomer indicates that the T=0 state of /sup 74 /Rb lies above the T=1 state. [...]

Average excited state lifetimes in /sup 73/Br / Asbo- Hansen, P ; Hagberg, E ; Hansen, P G ; Hardy, J C ; Jonson, B ; Mattsson, S
Lifetimes in the region of 10/sup -16/ s have been measured for excited states between 4 and 6.6 MeV in /sup 73/Br. The states were produced by the beta /sup +/(EC) decay of a mass-separated source of /sup 73/Kr, and they decayed by the emission of protons or gamma - rays; their lifetimes were measured by the particle X-ray coincidence technique.

Beta-delayed two-neutron and three-neutron emission / Jonson, B ; Gustafsson, Hans Åke ; Hansen, P G ; Hoff, P ; Larsson, P O ; Mattsson, S ; Nyman, G H ; Rvan, H L ; Schardt, D
Reviews experiments on /sup 11/Li that have led to the observation of two new active decay modes: beta-delayed two- and three-neutron emission. The 2n decay mode is also observed in /sup 30,31,32/Na and very recent results, reported for the first time, shown that it is detectable also in /sup 100/Rb with p/sub 2n//p/sub n/=0.027+or-0.007.

Particle unstable excited states in /sup 9/Be : influence of beta recoil and width on delayed particle spectra / Nyman, G H ; Azuma, R E ; Jonson, B ; Kratz, K L ; Larsson, P O ; Mattsson, S ; Ziegert, W
The light nucleus /sup 9/Be has been studied through the emission of beta-delayed neutrons and alpha particles from /sup 9/Li. The activity is produced at the ISOLDE facility in fragmentation reactions induced either by 600 MeV proton or 910 MeV /sup 3/He beams from the CERN Synchro-cyclotron. [...]

Comparative yields of alkali elements and thallium from uranium irradiated with high-energy protons, /sup 3/He and /sup 12/C / Gustafsson, Hans Åke ; Bjørnstad, T ; Jonson, B ; Jonsson, O C ; Lindfors, V ; Mattsson, S ; Poskanzer, A M ; Ravn, H L ; Schardt, D
Mass-separated ion beams of the alkali elements Na, K, and Fr, and of the element Tl are produced by bombarding a uranium target with 600 Me V protons, 890 MeV /sup 3/He/sup 2+/, and 936 MeV /sup 12/C/sup 4+/. Isotopic production yields are reported. [...]

Experiments on the nucleus /sup 100/Sr are reviewed. The activity was produced by fission with 600 MeV protons on a uranium target and after mass separation studied by gamma-ray and conversion-electron spectroscopy and by nanosecond lifetime measurements. [...]
