WebAs the best method to calculate r1 and r2 values, the Maximum Likelihood Method was taken. This method gave r1=0.495 and r2=0.467 where styrene is monomer 1. These values were then compared to the r1 and r2 values obtained from a Nonlinear Least Squares Method, Intersection Method, Fineman-Ross Method and the Kelen-Tudos Method.

WebAbstract in inglese. The 12 C (p,γ)13 N reaction has a crucial role in the determination of 12 C/13 C isotopic ratio in RGB and AGB H-shell. This ratio is a sensitive indicator of stellar nucleosysnthesis and useful tool to trace the galactic evolution. However, existing models cannot reproduce the observed 12 C/13 C isotopic ratio due to the ...
