Abstract

We report inversion of population between the ortho and para states of hydrogen at very low temperature with homogeneous external magnetic field. At low temperature, one needs to apply very high magnetic fields to get this population inversion when ortho states will be more populated than the para one. A numerical study of the change of bond length with magnetic field has been employed to find the precise field strengths at crossover points.
