| Outline of Final Research Achievements |
Parasitic laser ion source (PALIS) was proposed and installed in front of the slit at the second focal plane (F2) in RIKEN-RIBF fragment separator (BigRIPS). Unused RI-beams which are originally removed at the slits are collected and extracted as a low-energy RI-beams. The utilization of unused RI-beams is a new concept in the fragment separator facilities world wide. This system enable to perform both experimental styles: the production of low-energy RI-beam and also the measurement of nuclear electromagnetic moment by supersonic gas-jet laser spectroscopy. So far we confirmed the feasibility of PALIS experiment by the result which there was no interference to BigRIPS main beam experiment. By using wide variety rare RI-beams provided by BigRIPS, the PALIS system paves the way for the systematic study of wide variety nuclear electromagnetic momentｓ.
