| Outline of Final Research Achievements |
Observation of the emitted X-rays from muonic atoms is one of the most effective methods for the investigation of the nuclear charge distribution. Recently, a new method using solid hydrogen film has been developed to produce muonic atoms. However, several problems have to be solved before this method is applied to experiments for unstable nuclei. In this study, one such problem, concerned with handling of residual radioactivities in the film after experiments, was attacked experimentally using a radioisotope (RI) beam from KUR-ISOL and dry ice film.
An apparatus capable of implanting RIs to dry ice film and re-trapping the RIs with a cooled copper block was designed and installed at the beam line of KUR-ISOL.
It was observed that a relatively large number of the implanted RIs were transferred to the cooled block when the RIs were released with sublimation of dry ice. This technique can be applied to the deuterium film method when recovering residual radioactivities in film safely.
