The following nuclear reactions excited by protons on the stable boron isotopes are considered: <sup>10</sup>B(p,aγ)<sup>7</sup>Be, <sup>10</sup>B(p,pγ)<sup>7</sup>Be and <sup>11</sup>B(p,γ)<sup>12</sup>C. The optimum proton energy range was determined to be within 550 to 600&nbsp;keV, while the energies of the induced gamma-radiation that can be used for quantitative estimation of the boron isotopes were 429&nbsp;keV and 4439&nbsp;keV for the isotopes <sup>10</sup>B and <sup>11</sup>B, respectively. Considering the uncertainties of measurements, the data for the <sup>11</sup>B/<sup>10</sup>B&nbsp;isotope ratios, measured by the SF‑ICP‑MS and PIGE methods, are found to correlate with each other; yet they are characterized by a systematic bias. The uncertainty of measurements by the PIGE method was somewhat higher in comparison with SF-ICP-MS, and ranged from ±&nbsp;4.1&nbsp;% to ±&nbsp;4.3&nbsp;%, and from ±&nbsp;1.1&nbsp;% to ±&nbsp;3.5&nbsp;%, respectively.</p&gt;}, number={2}, journal={East European Journal of Physics}, author={Kutnii, Dmytro and Vanzha, Stanislav and Burdeynyi, Dmytro and Levenets, Volodymyr and Omelnik, O. and Shchur, A.}, year={2022}, month={Jun.}, pages={75-79} }
