Neutrino mas hierarchy value allow to distinguish between nh, ih, qd < mee> (100 – 500) meV – claim of an observation of 0 in 76Ge

Neutrino mas hierarchy value allow to distinguish between NH, IH, QD

• < mee> (100 – 500) meV – claim of an observation of 0 in 76Ge

• suggests quasi-degenerate spectrum of neutrino masses

• < mee> (20 – 55) meV – calculated using atmospheric neutrino oscillation parameters

• suggests inverted neutrino mass hierarchy or the normal-hierarchy – very near QD region

• < mee> (2 – 5) meV – calculated using solar neutrino oscillation parameters

• would suggest normal neutrino mass hierarchy
