Pair Emission from Excited Atoms

We explore a possibility of measuring the magnitude and the Majorana nature of neutrino masses, by using a novel process of neutrino pair emission from excited atoms. Except lepton number non-conserving processes, the neutrino pair (ν ¯ ν) emission is the unique process to distinguish the Ma-jorana neutrino from the Dirac neutrino. The small energy difference between atomic levels makes it easi...

Photoionization from excited Mg atoms

We present the theoretical results of a comprehensive study of the photoionization from excited Mg atoms in the spectral region below the Mg II 3p P limit using a B-spline-based configuration interaction approach. The variation of the doubly excited S , P , D , and F resonance structures along the autoionization series is discussed. The theoretical resonant energy and width, derived from the en...

Neutrino Pair Emission from Excited Atoms

We explore a possibility of measuring the absolute magnitude and the nature (Majorana vs Dirac) of neutrino masses, by using a novel process of neutrino pair emission from metastable excited atoms. Except lepton number non-conserving processes, the neutrino pair (ν ¯ ν) emission is the unique process to directly distinguish the Majorana neutrino from the Dirac neu-trino, using the interference ...

Fast metastable hydrogen atoms from H2 molecules: twin atoms

It is a difficult task to obtain “twin atoms”, i.e. pairs of massive particles such that one can perform experiments in the same fashion that is routinely done with “twin photons”. One possible route to obtain such pairs is by dissociating homonuclear diatomic molecules. We address this possibility by investigating the production of metastable H(2s) atoms coming from the dissociation of cold H2...
