“…We conclude this discussion by citing one example of the innovative use of SSNTD for the measurement of fission fragment angular distributions carried out at BARC (Chaudhuri et al 1979). Using a novel fission recoil chamber about the size of a , grape fruit' evolved from-considerations of neutron economy, it was possible to get the 14 MeV neutron fission fragment angular distributions of five independently fissioning actinide nuclei at a time.…”

Solid state nuclear track detectors (SSNTO) were introduced as an important research tool in nuclear science and technology in the early 1960s. In this paper an attempt is made to give an overview of some of the important applications of SSNTD in the study of fission-related phenomena. The areas covered are: (a) spontaneous fission half-lives, (b) compound nuclear lifetime measurements, (c) fission cross-section, excitation functions and fission fragment angular distributions, (d) fission isomers, (e) search for superheavy elements and (f) absolute fission yield measurements. In each case a few examples of experimental work carried out in various laboratories including the Bhabha Atomic Research Centre (BARe), Bombay are discussed to highlight the significant contributions these studies have made to our understanding of nuclei and nuclear fission. The important role played by SSNTD in each of the above areas of fission studies is illustrated. Some specific cases are cited where the innovative usc of SSNTD has lead to results of profound significance in fission physics. A general review of the impact of these studies on our present understanding of nuclei and nuclear fission as well as a brief outline of the problems and future prospects are also given in the paper.

“…It is worth pointing out here that the fission of 226Ra with tHe ions (compound nucleus 2~0~ ) gives a 'triple-humped' mass distribution with nearly equal contributions from both the symmetric and the asymmetric fission modes (Fairhall et al 1958). We conclude this discussion by citing one example of the innovative use of SSNTD for the measurement of fission fragment angular distributions carried out at BARC (Chaudhuri et al 1979). Using a novel fission recoil chamber about the size of a ' grape fruit' evolved from considerations of neutron economy, it was possible to get the 14 MeV neutron fission fragment angular distributions of five independently fissioning actinide nuclei at a time.…”

Solid state nuclear track detectors ($SNTD) were introduced as an important research tool in nuclear science and technology in the early 1960s. In this paper an attempt is made to give an overview of some of the important applications of SSNTD in the study of fission-related phenomena. The areas covered are: (a) spontaneous fission half-lives, (b) compound nuclear lifetime measurements, (c) fission cross-section, excitation functions and fission fra~nent angular distributions, (d) fission isomers, (e) search for superheavy elements and (f) absolute fission yield measurements. In each case a few examples of experimental work carried out in various laboratories including the Bhebha Atomic Research Centre (SARC), Bombay are discussed to highlight the significant contributions these studies have made to our understanding of nuclei and nuclear fission. The important role played by SSNTD in each of the above areas of fission studies is illustrated. Some specific cases are cited where the innovative use of ss~rrv has lead to results of profound significance in fission physics.
