We investigate a relation among neutrino observables, three mixing angles and two mass squared differences, from a cascade texture of neutrino mass matrix. We show an allowed region of the correlation by use of current data of neutrino oscillation experiments. The relation predicts sharp correlations among neutrino mixing angles as 0.315≲sin2θ12≲0.332 and 0.480≲sin2θ23≲0.500 with a large θ13 (0.03<sin22θ13<0.28). These magnitudes are modified 0.310≲sin2θ12≲0.330 and 0.540≲sin2θ23≲0.560 when the charged lepton mass matrix also has the cascade form. © 2011 Elsevier B.V.
