Investigation of electron localization in harmonic emission from asymmetric molecular ion |
(a) and (b) ((c) and (d)) time-frequency distributions for HeH2+ and HeD2+ at ν = 0 (at ν = 5) in a time range from t = 2.3 o.c. to t = 3.3 o.c., respectively. The insert shows the enlargement of time-frequency distributions from 250th order to 350th order. |
