| Research Abstract |
In this study, new collimators were designed and installed in the ANNRI. Using the collimators, the neutron beams are collimated to pencil beam with a diameter of 15 mm. Although beam intensity dropped to 1/25, the signal-to-noise ratio increased 3 times. The uncertainties of the obtained cross sections or curium isotopes are 5.8% at the top of the first resonance of ^<244>Cm and 6.6% at that of ^<246>Cm.
