The variational principle with a two-parameter trial wave function is used to determine the ionization energies and equilibrium internuclear separations of a hydrogen molecule ion situated in intense magnetic fields. The results for E1 obtained are improved significantly for fields less than 3 × 1010 G. and they approach the values predicted by de Melo, Ferreira, Brandi, and Miranda for very high fields.

The variational principle is used to determine the ionization energy and equilibrium internuclear separation of a hydrogen molecule ion in the presence of magnetic fields of strength up to [Formula: see text]. The trial wave functions used are made of some linear combinations of the unperturbed wave functions of the hydrogen atom. The results are shown to be better than those of de Melo, Ferreira, Brandi, and Mirandi for fields less than ~3 × 1010 G.

Neutron scattering in magnetic fields can provide important imformation regarding the magnetism of a system under study on microcsopic scale. Although pulse magnets are capable to reach very high fields, for neutron scattering mostly superconducting magnets are used. At present, a split-pair 14.5 T superconducting magnet used for user-program experiments at HMI offers the highest magnetic field for neutron scattering. With Dy-pole tips placed symmetrically around the sample position a 2.5 T enhancement is achieved. The temperature range accessible with such an insert is between 1.8 and 100 K. Temperatures down to 30 mK can be achieved with a dilution stick, which can be inserted into the 14.5 T cryomagnet. In the contribution we report on the latest neutron scattering achievements in magnetic fields obtained at HMI.

Abstract. We examine particularly intense substorms (SML ≤–2500 nT), hereafter called "supersubstorms" or SSS events, to identify their nature and their magnetic storm dependences. It is found that these intense substorms are typically isolated events and are only loosely related to magnetic storms. SSS events can occur during super (Dst ≤–250 nT) and intense (−100 nT ≥ Dst >–250) magnetic storms. SSS events can also occur during nonstorm (Dst ≥–50 nT) intervals. SSSs are important because the strongest ionospheric currents will flow during these events, potentially causing power outages on Earth. Several SSS examples are shown. SSS events appear to be externally triggered by small regions of very high density (~30 to 50 cm−3) solar wind plasma parcels (PPs) impinging upon the magnetosphere. Precursor southward interplanetary magnetic fields are detected prior to the PPs hitting the magnetosphere. Our hypothesis is that these southward fields input energy into the magnetosphere/magnetotail and the PPs trigger the release of the stored energy.
