In the hydrodynamical description of heavy-ion collisions, the elliptic flow 
and triangular flow 
are sensitive to the quadrupole deformation 
of the colliding nuclei. We produce and ratios qualitatively and quantitatively in most-central Xe–Xe collisions at 5.44 TeV. By employing HYDJET++ model, we study the sensitivity of anisotropic flow coefficients and mean transverse momentum to the quadrupole deformation and system-size in isotopic Xe–Xe collisions. Flow observables strongly depend on the strength of nucleon–nucleon scattering occurring in even-A and odd-A nuclei. Flow for odd-A nuclei is suppressed in comparison to flow in even-A collisions. There exists a linear inter-dependence between 
integrated anisotropic flow and nuclear deformation. Mean transverse momentum signifies the fireball temperature in body–body and tip–tip collisions. There exists a negative linear correlation of 
with collision system-size and a positive correlation with nuclear deformation. Flow measurements in high-energy, heavy-ion collisions using isotopic collision systems, offer a new precision tool to study nuclear structure physics. Observation of nuclear structure properties like nuclear deformation in a heavy-ion collision such as this would be very interesting.
