Production of 39Cl and 38S by photonuclear reactions using argon gas target

Recoil and implantation of radio-rhenium ions in poly- and single crystalline hexahalometal complexes

The (β', y) decay of 3 8 S a sa central atom of a sulphate ion leads for the major part to \" C I \" . Depending on the type of sulphate, about 2 1 2 % of the decays lead to the formation of higher oxidation states. The much lower yield of higher oxidation states for 3 CI produced by the 4 1 K(n , a ) 3 · C I reaction in the case of either K 2 S 0 4 or K,SO„ -K 2 BeF 4 , lends support to the assumption that decay produced 3 8 CI (with relatively low recoil energy) is sometimes left in sufficient proximity to the oxygen atoms of the original parent sulphate to lead to at least partial recombination. The probability was calculated that on nuclear recoil f rom the beta-decay of 3 8 S in sulphates the four original bonds with oxygen are preserved to yield 3 8 CIO; This probability was found to be very low in agreement with experimental values.
