Abstract

The excited states of 26 Al have been produced and studied using 27 Al(d,t) reaction with 25 MeV deuteron as projectile. Optical model potential parameters were extracted from the measured elastic scattering angular distribution. Zero range distorted wave Born approximation analysis for the ground and 0.223 MeV states of 26 Al have been done. The spectroscopic factors calculated for these states are found to be in good agreement with the previously reported values.

Highlights

2 Experimental procedureTransfer reaction provides a powerful tool to study the structure of nuclei
Well separated ridges corresponding to different outgoing particles as well as excited states corresponding to the nuclei 26Al, 26Mg and 25Mg produced via the reaction channels 27Al(d,t), 27Al(d,3He) and 27Al(d,α) are clearly seen in ΔE-(E+ΔE) scatter plot (Fig.1)
The parametric Wood Saxon (WS) form is used for optical model analysis for both real and imaginary potentials

Summary

Introduction

2 Experimental procedureTransfer reaction provides a powerful tool to study the structure of nuclei. Specific aspects of the structure of 26Al nucleus, e.g., excitation energies, spin and parity assignments, branching ratios, spectroscopic factors and life times are required. The spectroscopic strengths for these states were measured and reported in this work. Well separated ridges corresponding to different outgoing particles as well as excited states corresponding to the nuclei 26Al, 26Mg and 25Mg produced via the reaction channels 27Al(d,t), 27Al(d,3He) and 27Al(d,α) are clearly seen in ΔE-(E+ΔE) scatter plot (Fig.1).
