Summary
A methodology for extracting neutron direct capture rates from Coulomb Dissociation data is developed and applied to the Coulomb dissociation of ¹⁵C on ²°⁸Pb at 68 MeV/nucleon. Full Continuum Discretized Coupled Channel calculations are performed and an asymptotic normalization coefficient is determined from a fit to the breakup data. Direct neutron capture calculations using the extracted asymptotic normalization coefficient provide (n, γ) cross sections consistent with direct measurements. Our results show that the Coulomb Dissociation data can be reliably used for extracting the cross section for ¹⁴C(n,γ)¹⁵C if the appropriate reaction theory is used. The resulting error bars are of comparable magnitude to those from the direct measurement.
