According to Google Scholar, there have been 79 citations of that
paper. Likely, the true number of citations is higher.

A more recent paper that might be of interest is "Lunar Core and
Mantle. What Does LLR See?"

Although I was involved in LLR data analysis as a postdoctoral fellow
at MIT between 1979 and 1981, I concentrated on the intra-annual
variations in the length of day (and their association with changes in
atmospheric angular momentum) rather than the decadal and longer
variations. That work was written up in Nature.

Oh, to be a postdoc again (except for the low rate of pay)!
