This presentation covers how an established used of R-Matrix codes is being implemented at LANSCE. This presentation displays how there are unique features accessible with detectors at LANSCE that can be used to perform more complete R-Matrix analysis. Additionally discussed is how spin separation is a powerful technique that can be applied in DANCE measurements. Unique method to measure transmission with DICER are discussed. Finally, transmission and capture data are being analyzed in this work. The study can be extended to other channels. The ongoing analysis of the ¹⁴³Nd data is presented in this work. The same method is being applied to analyze the ^147,149Sm data. The ¹⁴³Nd and ^147,149Sm work started in FY-23 funded by NCSP.
