Nuclear constants for use in reactor activation analysis especially (n, ␥) cross-sections and absolute gamma intensities, are known to show a rather large scatter in literature. Thermal and resonance crosssections for the 75 As (n, ␥) 76 As reaction is determined by the method of foil activation usi

✦ Synopsis
A new method of enlarging the cross-section of KDP crystals using an easily enlarged ADP crystal as seed for a KDP crystal, has been investigated. The growth characteristics of the ADP seeds (Z-plate, cap, and parallelly spliced seeds) at KDP supersaturation have been observed. Chemical etching was used to characterize the grown crystals, and chemical analysis to determine the composition of both the region of the seed and the grown crystal. The mechanism of this kind of growth is discussed. In conclusion this growing method should be qualified for enlarging the cross-section of KDP crystals.
