Possibility of using Curium-248 for the development of the reference neutron sources
- V.G. Khlopin Radium Institute (Russian Federation); and others
Neutron sources on the base of {sup 252}Cf spontaneous fission are widely used. They have great specific neutron yields and comparative low gamma-ray background. But their half-lifes are rather short. The spectrum of {sup 252}Cf spontaneous fission neutrons was recommended by IAEA as an international standard spectrum. {sup 248}Cm is of special interest for a preparation on its base long-lived reference neutron sources. On the one hand its half-life (3.5 10{sup 5} years) is essentially greater than that of {sup 252}Cf (2.7 years), and on the other hand the intensity of {sup 248}Cm spontaneous fission is high enough (10{sup 4} fiss/mg s) which enables to use it in various scientific and practical purposes. For {sup 248}Cm there is practically information only about the middle energy of the spectrum. In this report the {sup 248}Cm spontaneous fission neutron spectrum measurement results are presented for the determination of the possibility of the use of this isotope as international standard and for purposes of a development of reference long-lived neutron sources on {sup 248}Cm base.
