An on-line mass separator for fission-produced alkali isotopes

1980

Abstract The design of an on-line mass separator installed at the TRIGA reactor in Mainz is described and its performance discussed. A tungsten oven, filled with about 2 g of 235U embedded in graphite, is exposed to a flux of 1.7 × 1011 thermal neutrons (s− cm−2) near the reactor core. After diffusion out of the graphite the fission-produced alkali isotopes are surface-ionized and electromagnetically mass-separated, the resolving power being about 750. Losses during the diffusion out of the target material are discussed. Due to these losses the maximum separator efficiency is about 5%, corresponding to a source strength of about 109 particles s−1 for the most abundant isotopes. The heaviest…

Evidence for anI=1 isomeric state in96Rb

1981

Aβ-RADOP (β-Radiation Detected Optical Pumping) experiment on the short lived (T1/2=203 ms)96Rb isotope has been performed at the on line mass separator for fission produced alkali isotopes at the TRIGA reactor in Mainz. Irradiation of r.f. onto the polarized sample to induce Zeeman transitions resulted in two signals for nuclear spinsI=2 andI=1. The previously undetermined component withI=1 is interpreted as evidence for an isomeric state in96Rb.
