英文摘要	we present photoelectron angular distribution of the aligned molecular ion h-2(+) by intense ultrashort attosecond extreme ultraviolet laser pulses from numerical solutions of time-dependent schrodinger equations. photoionization from a superposition state of the ground 1s sigma(g) and the excited 2p sigma(u) states with pulses at photon energies above the ionization potential, (h) over bar omega>i-p, and intensity 10(14) w/cm(2), yields pulse duration dependent asymmetry of photoelectron angular distributions. we attribute the asymmetry to the periodical oscillation of the coherent electron wave packets, resulting from the interference of the two electronic states. for the processes with long pulse durations, such duration dependence is absent and symmetric angular distributions are obtained.
