| Research Abstract |
Toward the observation of Feshbach resonance with a new mechanism, we developed anapparatus and to realize simultaneous laser-cooling and trapping of Rb and Sr. After the vacuum apparatus and laser system were developed, we demonstrated simultaneous magneto-optical trapping of Rb and Sr for the first time. Moreover, we found that the photoionization loss is dominant in simultaneous trapping of those atoms. Measuring the photoionization rate as varying the laser beam intensity results in the photoionization cross section of Rb in the 5 P_{3/2} state at a wavelength of 461 nm.
