Neutrino mass spectroscopy using Er${}^{3+}$ ions placed at inversion center of host crystals

H. Hara, N. Sasao, A. Yoshimi +1

We propose neutrino mass spectroscopy using Er${}^{3+}$:Cs${}_2$NaYF${}_6$ or :Y${}_2$O${}_3$ crystal placed in hollow of a Bragg fiber as a target system. Unknown neutrino parameters and pr…
