T-dependence and anisotropy of Knight shift and spin-lattice relaxation time T1 of In-NMR have been determined in heavy fermion superconductor CeIrIn. Knight shift and T1 show a strong anisotropy. Knight shift versus static susceptibility plot is non-linear at low temperatures, indicating that the hyperfine coupling depends on temperature. The origin of hyperfine interaction and anisotropy of spin fluctuations will be discussed.

In intense laser fields, molecules are decomposed into fragments through a number of competing dissociative ionization pathways. We investigate the dissociative ionization dynamics of ethanol in intense laser fields with photoelectron-photoion coincidence momentum imaging. The channel-specific photoelectron spectra reveal the electronic states prepared just after ionization, depending both on the decomposition pathways and on the temporal profile of laser pulses.

A guiding-centre fundamental 1-form whose symplectic part does not include the EB term is derived by the Lie-transform perturbation method. Since the symplectic part of the derived 1-form is the same as the standard one without the strong EB flow formally, it yields the standard Lagrange and Poisson brackets. Therefore the guiding-centre Hamilton equations also keep the standard form. The guiding-centre Hamiltonian is rather complicated compared to the previous ones. However, it is possible to simplify the Hamiltonian in localised transport barrier region like the tokamak H-mode edge.

We have developed a hybrid-anvil high-pressure device for single-crystal magnetic neutron diffraction beyond 3 GPa. The device consists of an opposed pair of an upper sapphire anvil and a lower WC anvil. Maximum pressure generated by the device is 7 GPa. To increase the maximum pressure up to 10 GPa, we tried three types of the lower anvil instead of the simple sapphire anvil. One is a sapphire anvil with a thin diamond cap, another is a sapphire anvil supported by a MP35 alloy, and the other is a SiC anvil supported by a MP35 alloy. We found that the modified hybrid-anvil, that is, the combination of the WC anvil and the supported SiC anvil could generate the pressure of 10 GPa at the load of 3.8 tons. The size of the sample chamber under 10 GPa was about 1 mm diameter and 0.25 mm height, which is sufficient for magnetic neutron diffraction experiments. We succeed in the magnetic neutron diffraction experiments on the RBC (R=Dy, Ho) up to 9 GPa with the modified hybrid-anvil device.

Chromatic and spherical aberrations are hindrance in a development of acceleration lens system to form the nanobeam with 1 MeV ion beam. However, chromatic and spherical aberrations are hindrance to form the nanobeam. Optics simulations were carried out to show that a combination of acceleration lenses and deceleration lenses is effective to reduce chromatic and spherical aberrations in the acceleration lens system. As a result, the deceleration energy of 15 keV for the 46 keV hydrogen molecule ion beam enabled us to reduce the chromatic aberration coefficient by 26 % and the spherical aberration coefficient by 17 %, and the beam current increased by 27 %.
