  We have implemented spherical harmonics in default Wood Saxon distribution of
the HIJING model and calculated various physical observables such as transverse
momentum, charged particle multiplicity, nuclear modification factor and
particle ratios for charged particles at top RHIC energy with collisions of
Uranium (U) nuclei. Results have been compared with available experimental
data. We observe that, a particular type of collision configuration can produce
significant magnitude change in observables. We have noticed that the tip-tip
configuration shows higher magnitude of particle yield in central collisions,
while the body-body configuration shows higher value in the cases of peripheral
collisions, with the flip in the trend occurring for the mid-central U+U
collisions. We observe that particle ratios are independent of configuration
type.
