We describe numerically the ionization process induced by linearly andcircularly polarized XUV attosecond laser pulses on an aligned atomic target,specifically, the excited stateNe$^*(1s^22s^22p^5[{}^2\text{P}^\text{o}_{1/2}]3s[^1\text{P}^o])$. We computethe excited atomic state by applying the time-dependent restricted-active-spaceself-consistent field (TD-RASSCF) method to fully account for the electroniccorrelation. We find that correlation-assisted ionization channels can dominateover channels accessible without correlation. We also observe that the rotationof the photoelectron momentum distribution by circularly polarized laser pulsescompared to the case of linear polarization can be explained in terms ofdifferences in accessible ionization channels. This study shows that it isessential to include electron correlation effects to obtain an accuratedescription of the photoelectron emission dynamics from aligned excited states.
