Considering the doubly magic nature of 
Pb nucleus, a large difference of the 
formation probability on the surface of 
Po and 
Po nuclei is expected. It is already confirmed that there exists a large gap in the decay lifetime of these nuclei. In this presentation, we theoretically describe the knockout reaction from these nuclei and consider the possibility of extracting the formation probability from the knockout cross section. A unique asymmetry of the momentum distribution which appears in the knockout reaction from heavy nuclei is also reported.

For development of spintronics applications in nuclear engineering, high energy swift ion irradiations on spin-Seebeck devices are achieved. The Tolerance of spin-Seebeck thermoelectricity of the devices against irradiation by swift heavy ions is tough enough under a harsh environment such as very close to a spent nuclear fuel.

In high-intensity proton accelerator, H
beams are injected with charge exchange into the ring by using a carbon foil. This scheme is destructive-type method and can accumulate high intensity proton beam. However, the uncontrolled beam losses by foil scattering and the foil breaking are a key issue in the world. In the J-PARC, we newly propose a laser stripping injection scheme of nondestructive-type method as an alternative to the foil and are under development for a proof-of-principle experiment of the method. We developed laser system and optical cavity and performed the second trial of the experiment. We were successfully matched laser pulse to ion beam one in time-space dimension. As this experimental result, we realized the charge exchange ratio of 16.8%, which is 30 times higher than first result of 0.57%. We present the experimental results with introducing the scheme.

At the J-PARC, a non-destructive method of "laser charge exchange injection" has been proposed and is under development to replace the carbon foil. In addition, the development of a non-destructive beam profile monitor is also important to stabilize the beam operation. In this study, we developed a laser source and a multi-pass cavity for this purpose, and performed the second experiment. In the development of the laser source, the timing of each of the five laser amplifiers was staggered, and we succeeded in producing a laser with a flat pulse structure. In the development of the multi-pass cavity, we succeeded in focusing 16 pulses of laser simultaneously to the irradiation point. As a result, a charge exchange efficiency of 16.8%, 30 times higher than the previous efficiency of 0.57%, was achieved. In this presentation, we report the results of the laser source development and the multi-pass cavity development.
