Description
The reaction $^{11}$B$(p,\alpha)\alpha\alpha$ is the primary mechanism for $^{11}$B burning in the stellar environment, which makes it a reaction of interest in nuclear astrophysics. Additionally, this fusion reaction is also relevant in nuclear fusion reactor development, promising clean energy and relatively simplified reactor engineering. The present work focuses on the cross section measurement of this fusion reaction with proton energies ranging from 300 keV to 2600 keV on the $^{11}$B target using the Extreme Light Infrastructure Silicon Strip Array (ELISSA). In the experimental set up we use two rings of 10 resistive Silicon Strip each in cylindrical configuration and double sided strip detectors in the back angles, covering an overall range of angles from 40$^{\circ}$ - 165$^{\circ}$. We observe the reaction populating the $\alpha_0$ and $\alpha_1$ channels from the sequential decay of $^{12}$C. The precise measurement of the total cross section of these channels can resolve the discrepancies in the existing measurements and can be further used as reliable input for future applications.
