Fig. 3: Statistics of the forward and backward ion yields/ratios as a function of the total ion yield.

a, c Statistics of the forward and backward ion yields as a function of the total ion yield for each single-shot measurements (c) is a zoomed in for the region at low total ion yields. Three different regions are discussed: â‘ forward emission is dominated; â‘¡ forward emission growth rate is suppressed and backward emission quickly surpassing forward emission; â‘¢ forward and backward proton yield tend to be consistent. b Statistics of the ratios of the forward and backward ion yields over total yields as a function of the total ion yield. d Statistics of forward and backward emitted protons for various excitation laser powers (the horizontal axis is displayed in log scale).
