Analyzing power of the neutron continuum spectrum for the 93Nb(→p, nX) reaction at 65 MeV and a DWBA analysis

The analyzing power of neutron continuum spectrum for the ⁹³Nb($\text{→p}$, nX) reaction at 65 MeV was measured for a wide angular range ?_n = 20° – 130°. The analyzing powers are positive and large at large angles ?_n > 40°. The characteristic features in the analyzing power for the ⁹³Nb($\text{→p, nX}$) reaction are very similar to those for the ⁹³Nb($\text{→p}$, p'X) reaction indicating the importance of a common reaction mechanism for both reactions. A DWBA calculation was performed and compared with the data. The calculation for E_X = 14 MeV reproduced the cross sections but failed to reproduce the analyzing powers.
