Title: ON RARE EARTH BORATES OF COMPOSITION 3R$sub 2$O$sub 3$ /center dot/ B$sub 2$O$sub 3$
Abstract: explain the observed discrepancy between the experimental levels of the /sup 1/D/sub 2/ and those calculated by Margolis. The interaction of 4f/sup 7/ with 4f/sup 6/6p is not large enough to explain the splitting of the /sup 1/P/sub 7/2/, and /sup 6/P/sub 5/2/ levels of GdCl/sub 3/. 6H/sub 2/O/ observed by Dieke and Leopold.
