摘要/Abstract

摘要： Using a full configuration-interaction method with Hylleraas-Gaussian basis function, this paper investigates the 1¹0⁺, 1¹(–1)⁺ and 1¹(–2)⁺ states of the hydrogen negative ion in strong magnetic fields. The total energies, electron detachment energies and derivatives of the total energy with respect to the magnetic field are presented as functions of magnetic field over a wide range of field strengths. Compared with the available theoretical data, the accuracy for the energies is enhanced significantly. The field regimes 3 < γ < 4 and 0.02 < γ < 0.05, in which the 1¹(–1)⁺ and 1¹(–2)⁺ states start to become bound, respectively, are also determined based on the calculated electron detachment energies.

Abstract: Using a full configuration-interaction method with Hylleraas--Gaussian basis function, this paper investigates the 1$^{1}$0$^{ + }$, 1$^{1}$(--1)$^{ + }$ and 1$^{1}$(--2)$^{ + }$ states of the hydrogen negative ion in strong magnetic fields. The total energies, electron detachment energies and derivatives of the total energy with respect to the magnetic field are presented as functions of magnetic field over a wide range of field strengths. Compared with the available theoretical data, the accuracy for the energies is enhanced significantly. The field regimes $3 < \gamma < 4$ and $0.02 < \gamma < 0.05$, in which the 1$^{1}$(--1)$^{ + }$ and 1$^{1}$(--2)$^{ + }$ states start to become bound, respectively, are also determined based on the calculated electron detachment energies.

Key words: strong magnetic field, hydrogen negative ion, total energy, electron detachment energy
