TITLE=/Analyzing power of the neutron continuum spectrum for the
93Nb(p,nX) reaction at 65 MeV and a DWBA analysis/;
PURPOSE=/To provide stringent test for various theories by simultaneous
fitting of analyzing powers as well as cross sections for both
neutron and proton spectra/;

- Time-of-flight (To determine outgoing neutron energy. The time
resolution (FWHM) of the beam burst was typically 1.0-1.5 ns, and
corresponding energy resolutions of the neutrons were about 4 and
2 MeV for 50 and 30 MeV neutrons, respectively.)
