چکیده
Analytical approximations are constructed for binding energies, quantum-mechanical sizes and oscillator strengths of main radiative transitions of hydrogen atoms arbitrarily moving in magnetic fields ∼ 10 12 − 10 13 G. Examples of using the obtained approximations for determination of maximum transverse velocity of an atom and for evaluation of absorption spectra in magnetic neutron star atmospheres are presented.

Hydrogen atom moving across a strong magnetic field: analytical approximations
Analytical approximations are constructed for binding energies, quantum-mechanical sizes and oscillator strengths of main radiative transitions of hydrogen atoms arbitrarily moving in magnetic fields ∼ 1012–1013 G.

متن کاملStructure and radiative transitions of the hydrogen atom moving in a strong magnetic field
The discrete specmm of the hydrogen atom moving acmss a stmng magnetic field (E = 7 x 10"-7 x IO'* G) is studied by expanding wavefunctions over a complete onhogonal basis, whose single term pmvides a correct description of an mmic state at large pseudomomenta K of the h'ansverse motion. Wavefunctions, energies, atomic sires and oscillator strengths of radiative transitions a~ calculated and an...
متن کاملMotion and ionization equilibrium of hydrogen atoms in a superstrong magnetic field.
We study the effects of finite proton mass on the energy levels of hydrogen atoms moving transverse to a superstrong magnetic field B with generalized pseudomomentum K⊥. Field strengths of order B ∼ 1012 Gauss are typically found on the surfaces of neutron stars, but we also study the regime B >∼ Bcrit = 4.23× 1013 Gauss, where the Landau excitation energy of the proton is large. We adopt two d...
متن کاملHydrogen Atoms in Neutron Star Atmospheres: Analytical Approximations for Binding Energies
Since the first observations of neutron stars thirty years ago, they have affected many branches of physics. These extremely compact stars serve as natural physical laboratories for probing the properties of matter under extreme physical conditions. In particular, more than half of them possess magnetic fields B > 10 G. Despite their name, neutron stars consist not only of neutrons. They have a...
متن کاملDiscrete eigenstates of the He + ion moving in a strong magnetic
We present precise results for the binding energies and sizes of the He + ion moving accross a strong pulsar-type magnetic eld. Similarly to the previously studied case of hydrogen, the ion is strongly deformed by the action of the motion-induced Stark forces. Unlike the case of the neutral hydrogen atom, whose transverse motion gives rise {for every discrete state of the non-moving atom{ to a ...
