In reference to recent experimental data, the dynamical cluster-decay model (DCM) has been applied to study the neutron evaporation residue (ER) cross sections of intermediate mass nucleus ⁹⁶Tc^{鈦?/sup> spread over a wide range of incident energy across the Coulomb barrier. In order to analyze the effect of rotational energy in the dynamics of 1" class="mathmlsrc">1-s2.0-S0375947414001158&_mathId=si1.gif&_user=111111111&_pii=S0375947414001158&_rdoc=1&_issn=03759474&md5=80b415576d99bbd96757e89e8dd5a28c">17" width="71" alt="View the MathML source" title="View the MathML source" src="/sd/grey_pxl.gif" data-inlimgeid="1-s2.0-S0375947414001158-si1.gif"> reaction, the cross sections have been calculated using the sticking (1-s2.0-S0375947414001158&_mathId=si2.gif&_user=111111111&_pii=S0375947414001158&_rdoc=1&_issn=03759474&md5=0300e1c8892629df89f4a02505bc47b2" title="Click to view the MathML source">I_S$I_S$) and the non-sticking (1-s2.0-S0375947414001158&_mathId=si3.gif&_user=111111111&_pii=S0375947414001158&_rdoc=1&_issn=03759474&md5=51b01ba9e5dff7bd340b75d6672e7c63" title="Click to view the MathML source">I_NS$I_{\mathit{NS}}$) limits of moment of inertia with inclusion of quadrupole (1-s2.0-S0375947414001158&_mathId=si4.gif&_user=111111111&_pii=S0375947414001158&_rdoc=1&_issn=03759474&md5=873cde3c86138dd21b04a0f3eb579abd" title="Click to view the MathML source">尾₂${\mathrm{<font\; color="red">尾</font>}}_2$) deformation within optimum orientation approach. The effect of either of the two approaches on the angular momentum, and hence the rotational energy associated with it, is assessed through the fragment mass distribution, preformation factor and the barrier penetrability. Also, the role of deformations is studied through a comparative analysis of decay path for spherical and 1-s2.0-S0375947414001158&_mathId=si4.gif&_user=111111111&_pii=S0375947414001158&_rdoc=1&_issn=03759474&md5=873cde3c86138dd21b04a0f3eb579abd" title="Click to view the MathML source">尾₂${\mathrm{<font\; color="red">尾</font>}}_2$ deformed fragmentation.
