摘要：We consider here the NOnA experiment configuration and propose to place a second off-axis detector,
with a shorter baseline, such that the type of neutrino mass hierarchy could be determined,
by exploiting matter effects, with only the neutrino run. We show that the determination of this
parameter is free of degeneracies, provided the ratio L E, where L the baseline and E is the neutrino
energy, is the same for both detectors. We also compare this possibility with the case of the
second detector placed at the second oscillation maximum.
