DESCRIPTION:Speakers: Alexey Eskin ()\nCoulomb systems of three particles\
 , consisting of an electron\, a negative muon and a nucleus\, are of signi
 ficant interest in many areas of physics\, including atomic spectroscopy a
 nd quantum electrodynamics. The ions of muonic lithium (µ e Li)\, berylli
 um (µ e Be)\, and boron (µ e B) include the simplest light nuclei behind
  hydrogen and helium. The lifetime of such ions is determined by the lifet
 ime of the negative muon. These bound states have a complex energy structu
 re\, which arises as a result of the Coulomb interaction of particles\, as
  well as the interaction of their magnetic moments. The interest in these 
 systems is due to the fact that the composite particles in them have very 
 different masses. As a result\, the muon and the nucleus form a quasi-nucl
 eus around which the electron moves\, and the three-particle system itself
  looks\, in the first approximation\, like a two-particle atom. The electr
 onic excited states 2S and 2P in such atoms can be investigated experiment
 ally. In any case\, such a program already exists for the muonic helium at
 om (µ e He). To calculate the energy levels in three-particle systems\, i
 n this work\, we use the stochastic variational method\, which has proven 
 itself in the study of hydrogen mesomolecules.\n\nhttps://indico.particle.
