“…In this respect, theoretical and experimental results show that hydrogen in atomic form is confined into octahedral and tetrahedral cavities of metals (Mg, Ti), metal clusters, alloys and inter-metallic compounds (e.g. LaNi 5 ) [17][18][19]. Moreover, polarizability studies under strong electric field require consideration of several values of proton displacement from the center of the cavity, something that has been considered only for a few cases so far [20].…”

In this paper the diffusion Monte Carlo method is applied to the confined hydrogen atom with different confinement geometries. This approach is validated using the much studied spherical and cylindrical confinements and then applied to cubical and squared ones, for which data are not available, as new applications of the method relevant to solid state physics. The energy eigenvalues of the ground state and one low-lying excited state are reported as a function of the characteristic confinement length.

“…Neutron elastic scattering experiments were performed using the high intensity total scattering spectrometer ͑HIT-II͒ installed at the spallation pulsed neutron source generated from a 500 MeV proton booster synchrotron at the High Energy Accelerator Research Organization KEK, Tsukuba, Japan. 5,6 Scattering intensities were measured individually for the samples, background, the empty cell, and a vanadium rod having the same dimensions as the cell. After corrections for background, absorption, multiple scattering, and incoherent scattering, the measured intensities were normalized to absolute units using the scattering, from the vanadium rod.…”

Neutron elastic scattering was used to determine the structure of as-received and lithiated amorphous SiO which has been proposed as an anode material for lithium ion secondary batteries. Based on a comparison between the total radial distribution functions ͓RDF(r)͔ of SiO and SiO 2 , it was suggested that amorphous SiO is composed of a three-dimensional SiO 4 tetrahedral network similar to silica (SiO 2 ) glass and metallic silicon clusters, and that the latter were finely dispersed in the SiO 4 matrix. On the other hand, electrochemically lithiated SiO showed a typical lithium negative correlation together with the disappearance of the Si-Si correlation in the RDF(r) which indicated that lithium predominantly reacted with the metallic silicon to form Li-Si alloys.

In this paper the Diffusion Monte Carlo (DMC) method is applied to the confined hydrogen atom with different confinement geometries. This approach is validated using the much studied spherical and cylindrical confinements and then applied to cubical and squared ones, for which data are not available, as new applications of the method relevant to solid state physics. The energy eigenvalues of the ground state and one low-lying excited state are reported as a function of the characteristic confinement length.
