  We identify here possible occurrence of large deformations in the neutron-
and proton-rich regions of the nuclear chart from extensive predictions of the
values of the reduced quadrupole transition probability B-E2 for the transition
from the ground state to the first 2+ state and the corresponding excitation
energy E2 of even-even nuclei in the recently developed Generalized
Differential Equation model exclusively meant for these physical quantities.
This is made possible from our analysis of the predicted values of these two
physical quantities and the corresponding deformation parameters derived from
them such as the quadrupole deformation beta-2, the ratio of beta-2 to the
Weisskopf single-particle beta-2 and the intrinsic electric quadruplole moment
, calculated for a large number of both known as well as hitherto unknown
even-even isotopes of Oxygen to Fermium (Z=8 to 100). Our critical analysis of
the resulting data convincingly support possible existence of large
collectivity for the nuclides 30,32 Ne, 34 Mg, 60 Ti, 42,62,64 Cr, 50,68 Fe,
52,72 Ni, 72,70,96 Kr, 74,76 Sr,78,80,106,108 Zr , 82,84,110,112 Mo, 140 Te,144
Xe, 148 Ba, 122 Ce, 128,156 Nd, 130,132,158,160 Sm and 138,162,164,166 Gd,
whose values of beta-2 are found to exceed 0.3 and even 0.4 in some cases. Our
findings of large deformations in the exotic neutron-rich regions support the
existence of another Island of Inversion in the heavy-mass region possibly
caused by breaking of the N=70 sub-shell closure.
