Query: Influence of higher-order deformations in the ^{34}S + ^{168}Er fusion
  reaction   The shape of the measured barrier distribution for the ^{34}S + ^{168}Er
reaction is analysed using the coupled-channels description. The ^{168}Er
nucleus is a good candidate to test current fusion models description of
deformation since it has a large quadrupole deformation with an insignificant
hexadecapole deformation. Coupling to weaker channels, the 2^+_1 state in
^{34}S, the 3^-_1 state in ^{168}Er, and the pair neutron transfer channel, all
were found to have little influence on the barrier distribution. A successful
description of the barrier distribution was only obtained after the
hexacontatetrapole deformation term in ^{168}Er (beta_6) was included in the
coupling scheme. However, a positive value for beta_6 was needed where the
macroscopic-microscopic model predicts a negative one.
