Abstract

Beams of unstable nuclei, ⁸Li and spin-polarized ¹²B, were introduced into superfluid helium and “snowballs”, aggregates of helium atoms surrounding the singly charged impurity ions, were formed through electrostriction. β-rays from the unstable nuclei encapsulated in the snowballs were detected after the snowballs were transported under an electrostatic field. It was found that approximately 20 % of the implanted ions formed snowballs. The spin polarization of ¹²B in snowballs was measured by β-NMR method. The first decisive evidence was obtained that the polarization was maintained throughout the lifetime of ¹²B (τ = 29 ms). The snowballs can be versatile environments for spectroscopic studies of unstable nuclei

Laser spectroscopy of Ag and Au atoms immersed in superfluid helium and its applications to investigate nuclear structures
2011, Physica E: Low-Dimensional Systems and Nanostructures
We have been developing a new nuclear laser spectroscopic method “OROCHI” for determining spins and moments of exotic RIs. It is the method based on the combination of superfluid helium as a stopper of radioactive isotope (RI) beam and in situ laser spectroscopy of RI atoms. This unique method will enable us to measure nuclear spins and electromagnetic moments of extremely low yield RI (less than 1 particle per second). For applying this method to stable Ag and Au isotopes, we have measured optical absorption spectra of these elements. Optical pumping of those atoms has also been attempted with pumping lasers tuned to the measured absorption lines. Details of this laser spectroscopy method in He II “OROCHI” and the development for applying OROCHI to Ag and Au atoms are presented.
Transport and extraction of radioactive ions stopped in superfluid helium
2003, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
A new approach to convert a high energy beam to a low energy one, which is essential for the next generation radioactive ion beam facilities, has been proposed and tested at Jyväskylä, Finland. An open ²²³Ra alpha-decay-recoil source has been used to produce radioactive ions in superfluid helium. The alpha spectra demonstrate that the recoiling ²¹⁹Rn ions have been extracted out of liquid helium. This first observation of the extraction of heavy positive ions across the superfluid helium surface was possible thanks to the high sensitivity of radioactivity detection. An efficiency of 36% was obtained for the ion extraction out of liquid helium.
Production of zero energy radioactive beams through extraction across superfluid helium surface
2003, Physica B: Condensed Matter
A radioactive $^{223} Ra$ source was immersed in superfluid helium at 1.2– $1.7 K$ . Electric fields transported recoiled $^{219} Rn$ ions in the form of snowballs to the surface and further extracted them across the surface. The ions were focussed onto an aluminium foil and alpha particle spectra were taken with a surface barrier spectrometer. This enabled us to determine the efficiency for each process unambiguously. The pulsed second sound wave proved effective in enhancing the extraction of positive ions from the surface. Thus we offer a novel method for study of impurities in superfluid helium and propose this method for production of zero energy nuclear beams for use at radioactive ion beam facilities.
