Modificated activation method for measurement of the yield of the astrophysical reactions

摘要

The original version of the activation method is presented and yield of the astrophysical relevant reaction 1 2 C ( p , γ ) 1 3 N has been measured at the energy region 190–650 keV using this method. The rate of this reaction was calculated within the temperature region 0 . 0 1 ≤ T 9 ≤ 1 . 0 through the yield values. The possibility of improving the method for measuring very small yields or cross sections was demonstrated.
