Abstract
The advantages of the use of molecular beams labeled with short lived (T½≈10−5−10−1 sec) nuclides in crossed beam studies of molecular interactions are discussed. Theoretical expressions useful for the design of effusive sources of such beams are presented. Experiments to verify the theory and develop apparatus capable of generating usefully intense beams are described, with particular reference to beams of HAt made with 0.032 sec 217At. Beams of 4×105 molecules/min incident on a spot 0.4 cm in diameter, 2.5 cm from the collimator, and with angular divergence of 4° have been achieved.This publication has 8 references indexed in Scilit:
