英文摘要	R-dependent high-order harmonic spectra (R is the nuclear distance) from H-2(+) have been investigated through solving the Non-Bohn-Oppenheimer time-dependent Schrodinger equation. We found that (i) for the case of the few-cycle pulse, the harmonic emission mainly occurs from R = 3.7 to R = 6, caused by the charge-resonance-enhanced-ionization (CREI) process. (ii) For the case of the multi-cycle pulse, the harmonic emission can be separated into two parts, that is the charge-resonance-enhanced ionization region from R = 3.7 to R = 8; and the dissociative ionization region when R> 10. (iii) Isotopic investigation showed that the R-dependent harmonic emission process can be moved towards the smaller-R region as the masses of the nuclei are increased (D-2(+) and T-2(+)). (iv) Multi-minima on the harmonic spectra can be obtained, which is attributed to the two-center interference and the electron nuclear coupling during the generation of the harmonics. The R-dependent ionization probabilities, the time-dependent nuclear motions and the time-frequency analyses of the harmonic spectra have been shown to explain the R-dependent molecular harmonic emission process.
