Measurement of total fission gamma spectrum of 252Cf(s.f.)

spectrum (TFGS) of 252Cf(s.f.) spanning an energy range from 0.2 to 14.3 MeV using stilbene scintillator spectroscopy. The measurement was performed with the 252Cf(s.f and the detector. The obtained spectrum was corrected for the e...

Position Sensitive Spectroscopy of Fission Fragments

We examine the response of Medipix2 to spontaneous fission products of 252Cf which are heavy-mass charged particles in the 40-120 MeV range. Measurements were made in vacuum using a thin source containing low activity of 252Cf....

Methodology of 63Cu(n,2n)62Cu Reaction Rate Measurement

This paper presents the measurement of the spectrum-averaged cross section (SACS) of 63Cu(n,2n)62Cu reaction in 252Cf spontaneous fission neutron spectrum. The SACS in the 252Cf spectrum was chosen as a validation tool since 252...

Spectrum averaged cross section measurements of lutetium using standard 252Cf neutron source

The spectrum averaged cross section (SACS) in a standard neutron field is a preferable tool for cross section validation. The presented work uses only neutron standard, i.e., 252Cf(sf) reaction neutron field, for validation of lutetium thres...

Measurement of the 23Na(n,2n) cross section in 235U and 252Cf fission neutron spectra

The presented paper aims to compare the calculated and experimental reaction rates of 23Na(n,2n)22Na in a well-defined reactor spectra and in the spontaneous fission spectrum of 252Cf. The experimentally determined reaction rate, derived usi...

High-energy neutron emission in thermal neutron-induced fission of 235 U

. The used prompt fission neutron fields correspond to the 252Cf(sf) and 235U(nth,f power reactors and the LVR-15 10 MWt reactor. The employed SACS in the 252Cf(sf ratio in 252Cf(sf) and 235U(nth,f) PFNS can be used to prob...

Comparison of experimental and calculated responses of CR-39 to neutron spectra of Am-Be and 252Cf sources.

Experimental values of response of CR-39 detector to monoenergetic neutrons were used to fit the response as a function of energy. Response to broad energy neutron spectra were calculated by means of this fit and compared to the experimental values (...
