Stellar Surface Abundance of Light Elements and Updated (p, $$\alpha $$ ) Reaction Rates

We present the progress in the measurements of the nuclear reaction rates for \(^{6,7}\)Li, \(^9\)Be and \(^{10}\)B (p,\(\alpha \)) burning channels derived using the Trojan Horse Method (THM). The effects on the predicted stellar surface abundances of such elements in pre-main sequence stars are evaluated using the Pisa up-to-date stellar evolutionary code. The present analysis is restricted to the pre-MS evolution of low-mass stars.
