OLIVARES PILON, H.. El ión molecular exótico H₄³⁺ en un campo magnético intenso. Rev. mex. fis. [online]. 2006, vol.52, n.2, pp.178-184. ISSN 0035-001X.

Using the variational method, a detailed study of the lowest m = 0,-1 electronic states of the exotic molecular ion H₄³⁺ in a strong magnetic field, in the linear symmetric configuration parallel to the direction of the magnetic field is carried out. A extended study of the 1σ_g ground state (J.C. Lopez and A.Turbiner, Phys. Rev. A 62, 022510, 2000) was performed obtaining that the potential energy curve displays a sufficiently deep minimum for finite internuclear distances, indicating the possible existence of the molecular ion H₄³⁺, for magnetic fields of strength B 3 x 10¹³ G. It is demonstrated that the excited state 1π_u can exist for a magnetic field B = 4.414 x 10¹³ G corresponding to the limit of applicability of the non-relativistic theory.
