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.
