The influence of the plasmon coupling on the orientation phenomena for the 1s{yields}2p{sub {+-}1} atomic collisional transitions is investigated in quantum plasmas. The effective Hamiltonan model taking into account the quantum and plasma shielding effects is applied to describe the electron-hydrogenic ion interaction in quantum plasmas. The semiclassical method is employed to describe the states of the projectile electron and target system in order to investigate the variation of the collisional orientation parameter as a function of the impact parameter, plasmon coupling parameter, collision energy, and Debye length. The variation and preference of the excitation probabilities due to the shielding and plasma coupling effects are also discussed.
