1. (n,2n) cross section measurement 2. Fission yield measurement 3. (n,n’g) and (n,2ng) measurement 4. Nuclear data benchmark experiments


(n,2n) cross section measurement A He-3 detector array composed of 80 He-3 counters

was constructed for measuring (n,2n) cross sections

• The detector is

ready!

• Efficiency

calibration for

Cf-252 source

finished!

• Waiting for in-

beam test.


Fission yield measurement

U-235

The fission yields of Zr-95, Zr-97, Mo-99, Ru-103, I-133, Ba-140 and Nd-147 for

U-235 induced by Cf-252 fission neutrons were measured.


Combined with our previous measurements, the energy dependent fission

yields were obtained.

Example of Nd-147


(n,n’g) and (n,2ng)measurement (n,n’g) and (n,2ng) for iron at 14 MeV, (n,n’g) for U-238 at 14 MeV have been

obtained.
