We investigate the 
decay width of excited charmonium states at finite nuclear density with simultaneous modification of both D- and 
-mesons in nuclear matter. The strongest effect is found for the 
-meson. The medium modification can be detected by dilepton spectroscopy as substantial broadening and anomalous absorption.
