摘要

研究了带电粒子在弱磁场中的准经典动力学，以及介质电离引起的耗散损失。本文提出的近似方法是卡尔迪罗拉-卡奈方法的一般化，用于量化粒子在耗散介质中的平移运动。研究表明，磁场对经典轨迹产生微弱曲率的同时，粒子坐标的不确定性会各向同性地增加，在局部概率密度波包停止的瞬间达到某个最大值。坐标不确定性增加的限制是由于不可逆转的电离损耗造成的。

Quasi-classical dynamics of a charged particle under conditions of ionization losses in a weak magnetic field

The quasi-classical dynamics of a charged particle in a weak magnetic field in the presence of dissipative losses caused by ionization of the medium is studied. The approximate approach proposed here is a generalization of the Caldirola—Kanai method for quantizing the translational motion of particles in dissipative media. It is shown that a weak curvature of a classical trajectory by the magnetic field is accompanied by an isotropic increase of uncertainty of the particle coordinates to the some maximum value at the moment the localized probability density wave packet stops. The limitation of the increase of coordinate uncertainty is due to irreversible ionization losses.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
