A New Technique to Measure Double-differential Charged-particle Emission Cross Sections Using Pencil-beam DT Neutrons

摘要

For precise measurement of Double-differential Charged-particle Emission Cross Section(DDXc), a unique technique was developed. Utilizing an anticoincidence spectrum successfully extended lower limit of measurable energy for α-particle. The validity of the present technique was confirmed from the result that the obtained total cross section agreed with the evaluated value of ~(27)Al(n,xα) reactions. The measurements for beryllium were carried out. The results suggested more detailed analysis for ~9Be(n, charged particle) reactions was required.
