Measurement of ⁸⁵Rb(n, 2n)^84mRb reaction cross-section at 15.72±0.59 and 16.73±0.66 MeV

The cross-section of ⁸⁵ Rb (n, 2n) ^84m Rb has been measured at neutron energies of 15.72±0.59 MeV and 16.73±0.66 MeV using activation and off-line γ-ray spectrometry technique. The experimental work was carried out at 14UD BARC-TIFR Pelletron facility. Fast neutrons were produced by the ⁷ Li(p, n) ⁷ Be reaction. ²⁷ Al(n, α) ²⁴ Na reaction is used to determine the neutron flux. The induced γ-ray activity in the reaction products was measured using high purity Germanium (Ge) detector.
