It introduces a combined analysis approach to improve the accuracy of nuclear level width measurements in nitrogen-15.

Findings

Revised widths show discrepancies with previous adopted values.

Combined data analysis enhances measurement precision.

Identifies inconsistencies in existing nuclear data for $^{15}$N.

Abstract

The determination of absolute widths of two observed levels above the proton threshold in $^{15}$N has been improved by a combined analysis of our recent $^{15}$N($\gamma$,$\gamma'$)$^{15}$N$^\ast$ photon scattering data, resonance strengths $\omega\gamma$ of the $^{14}$C($p$,$\gamma$)$^{15}$N reaction, and $\gamma$-ray branchings $b_{\gamma,i}$ in $^{15}$N. The revised data are compared to the adopted values, and some inconsistencies in the adopted values are illustrated.
