Abstract
In the case of rather strong exchange, we have used a method already p ublished by two of us in order to determine for the Rb compound J'/k=( 0.28+/-0.03) K. In the case of rather weak exchange, we have used a me thod proposed by Hoffmann in order to determine J'/k=(0.050+/-0.002) K for the K compound and J'/k=(0.058+/-0.002) K for the NH4 compound
