Proton spin–lattice relaxation time in ordering VHx alloys Original Research Article

Proton spin–lattice relaxation time is determined in VH0.68 and VH0.73 alloys in the temperature range of β1, β2 and δ ordered phases (400–100 K). Experimental results are described in terms of dipole–dipole interaction mechanism. On comparing calculated and experimental data in the complete temperature range the values of temperature dependent activation energy Ea and time constant τ0 are estimated.
