Abstract:

The exotic system H ₃ ⁺⁺ (which does not exist without magnetic field) exists in strong magnetic fields:

In triangular configuration for B≍10⁸-10¹¹ G (under specific external conditions) </ItemContent> </ListItem> <ListItem> <ItemNumber>(b)</ItemNumber> <ItemContent>

In linear configuration for B>10¹⁰ G </ItemContent> </ListItem> </OrderedList> </ItemContent> </ListItem> <ListItem> <ItemNumber>2.</ItemNumber> <ItemContent>

In the linear configuration the positive z-parity states 1σ _g, 1π _u, 1δ _g are bound states </ItemContent> </ListItem> <ListItem> <ItemNumber>3.</ItemNumber> <ItemContent>

In the linear configuration the negative z-parity states 1σ _u, 1π _g, 1δ _u are repulsive states </ItemContent> </ListItem> <ListItem> <ItemNumber>4.</ItemNumber> <ItemContent>

The H ₃ ⁺⁺ molecular ion is the most bound one-electron system made from protons at B>3×10¹³ G </ItemContent> </ListItem> </OrderedList> Possible application: The H ₃ ⁺⁺ molecular ion may appear as a component of a neutron star atmosphere under a strong surface magnetic field B=10¹²-10¹³ G.
