摘要：A distribution form of number of small developed silver specks was measured at sulfur + gold-sensitized emulsions by the arrested development technique. The distribution form obeys the Poisson distribution law even at the lowest sensitization level, while sulfur-sensitized emulsion shows the distribution form of one speck per one grain at much higher level of sensitization. Sulfur + gold sensitization specks act as effective electron traps to form latent image specks. Efficiency of formation of the effective electron traps is higher at the sulfur +gold sensitization treatment than the sulfur sensitization alone.
