Determination of the asymptotic normalization coefficients for ¹⁴C + n ←→ ¹⁵C, the (+14)C(n, γ)¹⁵C reaction rate, and evaluation of a new method to determine spectroscopic factors

NUCLEAR REACTIONS ¹³C(¹⁴C, ¹⁴C), (¹⁴C, ¹⁵C)¹²C, E=12 MeV/nucleon; ²H(¹⁴C, p)¹⁵C, E=11.7 MeV/nucleon; ¹⁴C(d, p), E=60 MeV; measured particle spectra, σ(θ) using MDM spectrometer at Texas A-M Cyclotron Institute. ¹⁵C; deduced levels, asymptotic normalization coefficient (ANC) and spectroscopic factors for g.s. and first excited state. ¹³C, ¹⁷O; population of g.s. in both and excited levels in ¹³C. DWBA analysis with Woods-Saxon and doublefolding (DF) potentials for ¹³C+¹⁴C reaction. FRESCO code and adiabatic distorted wave approximation (ADWA) used for analysis of σ(θ) data in ²H+¹⁴C reactions. ¹⁵C, ¹⁵F; analyzed mirror analogy for spectroscopic factors. Deuteron stripping theory. ¹⁴C(n, γ), E=10 keV-1 MeV; deduced astrophysical direct-capture rate σ(E) to g.s. and first excited state using RADCAP code and ANCs from the present work. Comparison with previous experimental results.
