244Pu, 241Am, and 243Am PURPOSE=/ The aim is to study more extensively the systematic variation of mass yield curves as a function of the (Z,N) of the fissioning nucleus and excitation energy in order to elucidate how strongry some basic physical quantities affect the mass division in fission. /; ATH=(T.OHTSUKI'1,2', Y.NAGAME'2', K.TSUKADA'1', N.SHINOHARA'2', S.BABA'2', K.HASHIMOTO'2',
