    Measurement of 14.54 ± 0.24 MeV neutron activation reaction cross sections of 93Nb, natMo with covariance analysis
    (Springer Netherlands rbk@louisiana.edu, 2020) Pasha, I.; Rudraswamy, R.; Yerranguntla, S.S.; Suryanarayana, S.V.; Pachuau, R.; Midhun, C.V.; Naik, H.; Patel, T.; Bishnoi, S.; Danu, L.S.
    The 93Nb(n,?)90mY, 93Nb(n,2n)92mNb and 92Mo(n,p)92mNb reaction cross sections have been measured relative to the 197Au(n,2n)196Au monitor reaction at the neutron energy of 14.54 ± 0.24 MeV. The neutrons were generated from the T(d,n)4He reaction using Purnima neutron generator. The experiment was done by using the method of activation in combination with an off-line ?-ray spectrometry technique. The uncertainties and correlations for the reaction cross sections were estimated with the use of covariance analysis by considering the partial uncertainties in individual attributes. The measured reaction cross sections have been analyzed by comparing with the data available in EXFOR compilation, various files of evaluated data and theoretically calculated values from TALYS-1.9. © 2020, Akadémiai Kiadó, Budapest, Hungary.

    Measurement of 67Zn(n,p)67Cu, 64Zn(n,2n)63Zn, 89Y(n,?)90mY and 89Y(n,2n)88Y reaction cross sections at the neutron energy of 14.54 MeV with covariance analysis
    (Springer Netherlands rbk@louisiana.edu, 2019) Pasha, I.; Rudraswamy, R.; Yerranguntla, S.S.; Suryanarayana, S.V.; Naik, H.; Karkera, M.; Eswaran, R.; Gurusamy, P.; Madegowda, S.A.; Basavalingappa, S.H.
    The 67Zn(n,p)67Cu, 64Zn(n,2n)63Zn, 89Y(n,?)90mY and 89Y(n,2n)88Y reaction cross sections relative to the 197Au(n,2n)196Au monitor reaction have been determined at the neutron energy of 14.54 ± 0.002 MeV by using the method of activation and off-line ?-ray spectrometry. The neutron energy used was obtained from the 3H(d,n)4He reaction. The covariance analysis was performed by taking the uncertainties arising in various attributes and the correlations between those attributes. The analyzed results from the present measurement were compared with the literature data and evaluated data of various libraries like ENDF/B-VIII, JEFF-3.3, JENDL-4.0 and ROSFOND-2010 libraries as well as with the calculated values based on TALYS-1.9 code. © 2019, Akadémiai Kiadó, Budapest, Hungary.
