“…The nuclear track technique has come a long way since its inception three decades ago (Young, 1958). It has been successfully applied to many fields like the development of microfilters (Fleischer et al, 1963;Vater, 1988 and references therein), the study of nuclear reactions (Price and Walker, 1962;Khan, 1985;Gottschalk et al, 1979) fusion-fission phenomenon (Debeauvais and Ralarosy, 1983;Dwivedi and Fiedler, 1988;Dwivedi et al, 1993a) and to areas such as archaeological, geological and cosmological sciences (Fleischer et al, 1975). Newly emerged technological applications involving microstructuring and heavy ion lithography (Spohr, 1990) have great applied value.…”
