Ablation of frozen acetone targets by synchrotron radiation produced a
variety of deposits in the forms of films or particles (round, glass
pieces, needle or flat plate). From one of the deposits we observed a
sharp Raman peak at 1333 cm(-1), indicating the formation of diamond.
However, this result could not be reproduced. Sharp Raman peaks were a
lso observed near 500 cm(-1) from the deposits shaped like glass piece
