Fission yield measurements with the ISOL method / ISOLDE Collaboration
Radioactive ion beam intensities have been measured at ISOL (isotope separation on-line) facilities from many different targets, but only rarely these intensities are converted into production cross-sections. Here we discuss the method and possible problems in this conversion at the examples of Kr and Xe produced by 1.4 GeV-proton-induced fission of 238U at ISOLDE and Rb and Cs produced by approx. [...]

Photofission for the production of radioactive beams : experimental data from an on-line measurement / Ibrahim, F ; Obert, J ; Bajeat, O ; Buhour, J M ; Carminati, D ; Clapier, F ; Donzaud, C ; Ducourtieux, M ; Dufour, Jean Marie ; Essabaa, S et al.
A PARRNe 1 experiment (Production d'Atomes Radioactifs Riches en Neutrons) aimed at the production of neutron-rich radioactive noble gases produced by photofission has been performed at CERN. The LEP Pre-Injector (LPI) has been used to deliver a 50 MeV electron beam. [...]

In order to probe neutron rich radioactive noble gases produced by photo-fission, a PARRNe-1 experiment (Production d'Atomes Radioactifs Riches en Neutrons) has been carried out at CERN. The incident electron beam of 50 MeV was delivered by the LIL machine: LEP Injector Linac. [...]

Production yields of noble-gas isotopes from ISOLDE UC$_{x}$/graphite targets / ISOLDE Collaboration
Yields of He, Ne, Ar, Kr and Xe isotopic chains were measured from UC$_{x}$/graphite and ThC$_{x}$/graphite targets at the PSB-ISOLDE facility at CERN using isobaric selectivity achieved by the combination of a plasma-discharge ion source with a water-cooled transfer line. %The measured half-lives allowed %to calculate the decay losses of neutron-rich isotopes in the %target and ion-source system, and thus to obtain information on the in-target %productions from the measured yields.

Beta-decay properties of the neutron-rich $^{94-99}$Kr and $^{142-147}$Xe isotopes / ISOLDE Collaboration
Beta-decay half-lives and delayed-neutron emission probabilities of the neutron-rich noble-gas isotopes $^{94-99}$Kr and $^{142- 147}$Xe have been measured at the PSB-ISOLDE facility at CERN. The results are compared to QRPA shell-model predictions and are used in dynamic calculations of r-process abundances of Kr and Xe isotopes..

Studies of release properties of ISOLDE targets / Peräjärvi, K ; Bergmann, U C ; Fedosseev, V ; Joinet, A ; Köster, U ; Lau, C ; Lettry, Jacques ; Ravn, H L ; Santana-Leitner, M /ISOLDE Collaboration
Off-line release rates of Be, Mg, S, Mn and Kr from refractory materials were studied. Mn yields were determined from a ZrO2 target and Kr yields from a SrO and ZrO2 targets. [...]

Yields of neutron-rich rubidium and cesium isotopes from fast-neutron induced fission of $^{238}$U, obtained by studying their release from a thick ISOL target / Hosni, F ; Lau, C ; Bajeat, O
In the framework of the EURISOL project, the production of neutron-rich isotopes of rubidium and cesium has been studied. The intensities of mass-separated beams of rubidium and cesium isotopes generated from a thick 238UCx target connected to a surface ionizer have been measured. [...]
