Abstract

Laser spectroscopy measurements have been carried out on the very neutron-rich tin isotopes with the COMPLIS experimental setup. Using the 5s25p2 3P0 → 5s25p6s 3P1 optical transition, hyperfine spectra of 126–132Sn and 125m,127m,129m–131mSn where recorded for the first time. The variation of the mean square charge radius (δ 〈 r2 〉) between these nuclei and the nuclear moments of the isomers and the odd isotopes were thus measured. From the quadrupole moments values, all these nuclei appear to be spherical. The experimental magnetic moments are thus compared with the Schmidt values calculations. Moreover, the measured δ 〈 r2 〉 are compared with several mean field calculations. [Copyright &y& Elsevier]

Abstract

The diffusion properties of graphite targets with 1, 4 and 15 microns microstructure has been measured for He and Ar isotopes. An important enhancement of the diffusion efficiency for the smaller microstructure is observed. A releasing efficiency of the order of 100% was obtained for 6He (T1/2=806 ms) at a temperature of 1600 K. The diffusion and production properties of He isotopes in a target of B4C (boron carbide) have also been studied. Yields of 1.4×108 pps and 5.0×105 pps for 6He and 8He has been obtained.
