  An intense study of the alpha decay properties of the isotopes of superheavy
element Z=113 have been performed within the Coulomb and proximity potential
model for deformed nuclei (CPPMDN) within the wide range 255 l.e. A l.e. 314.
The predicted alpha decay half lives of $^{278}$113 and $^{282}$113 and the
alpha half lives of their decay products are in good agreement with the
experimental data. 6{\alpha) chains and 4{\alpha} chains predicted respectively
for $^{278}$113 and $^{282}$113 are in agreement with the experimental
observation. Our study shows that the isotopes in the mass range 278 l.e. A
l.e. 286 will survive fission and can be synthesized and detected in the
laboratory via alpha decay. In our study, we have predicted 6{\alpha} chains
from $^{279}$113, 4{\alpha} chains from $^{286}$113, 3{\alpha} chains from
$^{280,281,283}$113, 2{\alpha} chains from $^{284}$113 and 1{\alpha} chain from
$^{285}$113. We hope that these predictions will be a guideline for future
experimental investigations.
