Cross-section data of the 185Re(n,2n)184mRe,185Re(n,2n)184gRe,185Re(n,α)182m1+m2+gTa,187Re(n,2n)186g,(m)Re,187Re(n,α)184Ta,and 187Re(n,p)187W reactions were measured at four neutron energies,namely 13.5,14.1,14.4,and 14.8 MeV,by means of the activation technique,relative to the reference cross-section values of the 93Nb(n,2n)92mNb reaction.The neutrons were generated from the T(d,n)4He reaction at the K-400 Neutron Generator at China Academy of Engineering Physics.The induced γ activities were measured using a high-resolution γ-ray spectrometer equipped with a coaxial high-purity germanium detector.The excitation functions of the six above-mentioned nuclear reactions at neutron energies from the threshold to 20 MeV were calculated by adopting the nuc-lear theoretical model program system Talys-1.9 with the relevant parameters properly adjusted.The measured cross sections were analyzed and compared with previous experiments conducted by other researchers,and with the evalu-ated data of BROND-3.1,ENDF/B-Ⅷ.0,JEFF-3.3,and the theoretical values based on Talys-l.9.The new meas-ured results agree with those of previous experiments and the theoretical excitation curve at the corresponding ener-gies.The theoretical excitation curves based on Talys-1.9 generally match most of experimental data well.

Super-entropic black holes possess finite-area but noncompact event horizons and violate the reverse iso-perimetric inequality.It has been conjectured that such black holes always have negative specific heat at constant volume CV or negative specific heat
