  The evaporation residue (ER) cross section of 3n and 4n channels related to
the synthesis of superheavy element (SHE) with the charge number $Z=119$ in the
$^{51}$V+$^{248}$Cm reaction has been calculated by the dinuclear system (DNS)
model as a sum of the partial cross sections of the corresponding channels. The
angular momentum distribution of the compound nucleus is estimated by the
dynamical trajectory calculations of the capture probability which is
considered as the DNS formation probability. The fusion probability decreases
by the increase of the DNS angular momentum due to its influence on the
intrinsic fusion barrier $B_{\rm fus}^*$. The range $\alpha_2=60^{\circ} \div
70^{\circ}$ of the orientation angle of the axial symmetry axis of the deformed
target nucleus $^{248}$Cm is favorable for the formation of the compound
nucleus. The fusion probability decreases at around $\alpha_2=90^{\circ}$ since
the number of the partial waves contributing to the capture decreases.
Therefore, it is important to calculate the capture cross section dynamically.
The 4n channel cross section of the SHE synthesis is larger than the 3n channel
cross section maximum value of the ER cross section is 12.3 fb at $E_{\rm
c.m.}$=232 MeV.
