  In this work study on alpha decay chains emerging from isotopes of Z = 122
superheavy nuclei is carried out with emphasize on nuclear deformations and
Langer modification. The interest in this particular superheavy nuclei is due
to the recent experimental efforts to synthesize the isotope ^{299}120 in a
fusion reaction at the velocity filter SHIP (GSI Darmstadt), which makes
synthesis of Z = 122 nuclei to occur in the near future, and in turn will give
the experimentalist the chance observe the decays associated with the isotopes
of this nuclei. We perform our calculations by choosing the Woods Saxon
potential for nuclear interaction, along with Coulomb potential and centrifugal
potential within the framework of the WKB method. When the centrifugal term is
taken in the total potential and WKB integral is done over 1D radial
coordinate, it requires the use of Langer modification wherein (l + 1/2 )^2
replaces l(l +1) for consistency of WKB wave function. Hence we have used this
Langer modified centrifugal potential. The orientations of deformed nuclei are
important, as it affects the touching distance and also influence the nuclear
and Coulomb potential, and thus can alter the values of penetration integral
and half-life. The results obtained by our calculations are in agreement with
the values obtained from various phenomenological models. This study brings out
the unique characteristics of alpha chains associated with each isotope, which
will be helpful for the experimentalist to decide the isotope they would like
to synthesize and also for their post-synthesis study.
