neutrinoless double-electron capture
要旨:
Rapidly developing neutrino physics has found in Penning-trap mass spectrometry a staunch ally in investigating a variety of fundamental problems. The most familiar are the absolute neutrino mass, possible existence of resonant neutrinoless double-electron capture and of keV-sterile neutrinos, and investigation of neutrino oscillations. This article is a brief review of the latest achievements and future perspectives of Penning-trap mass spectrometry in the exploration of these problems with a focus on electron capture and double electron capture processes.
