| Research Abstract |
We produced a new type of velocity decelerator which is constructed with 200sets of asymmetrically spatial modulated magnetic fields by using neodymium magnets. For the performance examination of the designed decelerator, we studied the action of the velocity decelerator on the metastable He(3S). The velocity distribution of He(3S) after passing the velocity modulator separates into three components, which correspond to the three different magnetic quantum number(M) states. It is verified that we succeeded in the state selection of the paramagnetic species by deceleration and acceleration of the velocity depending on the quantum state.
