Times Cited Count:1 Percentile:11.48(Physics, Nuclear)High-spin states in Pt have been investigated by means of in beam
-ray spectroscopic method at the JAEA tandem facility. Low-spin signature inversion is revealed in the 7/2
[503] band. The inversion can be interpreted as a configuration change from the 7/2
[503] orbital to the 7/2
[514] orbital with increasing spin, which is supported by a theoretical calculation of the semi-classical Donau and Frauendorf approach.

Times Cited Count:37 Percentile:75.06(Physics, Fluids & Plasmas)An experiment for the laser self-guiding studies has been carried out with 100 TW laser pulse interaction with the long underdense plasma. Formation of extremely long plasma channel with its length, about 10 mm, 20 times above the Rayleigh length is observed. The self-focusing channel features such as the laser pulse significant bending and the electron cavity formation are demonstrated experimentally for the first time.

First experiments for electron acceleration with the laser-gas plasma interaction have been carried out with 30 fs, 100 TW relativistic Ti:Sapphier laser pulse into a long slit (1.2 10 mm
) gas plasma. The 10 mm length plasma channel formed that was longer than 20 times the Rayleigh length. Plasma density was the key factor for this long channel stimulation under 100 TW laser pulse irradiation that was much higher than critical power for relativistic self-focusing. For the first time, channel characteristics such as laser bending, hosing and cavity formation were demonstrated experimentally. In case of long channel guiding, accelerated electron bunch was tightly collimated with low emmitance
mm mrad and quasi-monoenergetic electron bunch (
70 MeV) was obtained as well. Accelerated electron charge current with electron energy
1 MeV was
10 nC/shot which was highest value in laser accelerator, to our knowledge, and ascribed to the contribution of long plasma channel. These well controlled laser-driven acceleration is an important cornerstone of relativistic engineering.
