摘要

The paper is focusing on the modification of the crystal lattice upon the hydrogenation of La_2Pd_2In and hydrogen desorption from La_2Pd_2In hydrides. The synthesis at 1 bar of hydrogen produces a crystalline hydride with 1.5 H atoms per formula unit and the volume expansion of AV/V=6.0%. The synthesis at 10 and 100 bar H_2 pressures leads to an amorphous state and with 4 + 8 H atoms/f.u. The uptake of hydrogen leads to the decrease of the Debye temperature of La_2Pd_2In and modification of the optical phonon spectrum.
