Fig. 2: Comparison of gamma-ray spectra with simulation.
a Gamma-ray spectrum observed in coincidence with the two-neutron knockout reaction 9Be(86Mo, 84Moγ). A simulated spectrum with τ(\({2}_{1}^{+}\)) = 27.1 ps (red line) is drawn for comparison. The energies of the \({2}_{1}^{+}\to {0}_{1}^{+}\) and \({4}_{1}^{+}\to {2}_{1}^{+}\) transitions are 443.9 keV and 673.4 keV50, respectively. b Gamma-ray spectrum observed in coincidence with the inelastic excitation of 86Mo. A simulated spectrum with τ(\({2}_{1}^{+}\))=19.9 ps (red line) is drawn for comparison. The energies of the \({2}_{1}^{+}\to {0}_{1}^{+}\) and \({4}_{1}^{+}\to {2}_{1}^{+}\) transitions are 566.6 keV and 760.9 keV, respectively51. The error bars show the 1σ statistical uncertainty. The fast and slow components of the Doppler corrected photopeaks are labeled "F” and “S'', respectively.
