Zusammenfassung: <jats:title>Abstract</jats:title> <jats:p>Preliminary results of measurements of the total reaction cross sections σ<jats:sub>R</jats:sub> for nuclei <jats:sup>4</jats:sup>He, <jats:sup>6</jats:sup>He, <jats:sup>8</jats:sup>He, <jats:sup>7</jats:sup>Li, <jats:sup>8</jats:sup>Li, <jats:sup>9</jats:sup>Li, <jats:sup>1</jats:sup>Li, <jats:sup>11</jats:sup>Be, <jats:sup>9</jats:sup>Be, <jats:sup>10</jats:sup>Be, <jats:sup>11</jats:sup>Be, <jats:sup>12</jats:sup>Be, <jats:sup>8</jats:sup>B, <jats:sup>10</jats:sup>B, <jats:sup>11</jats:sup>B and <jats:sup>12</jats:sup>B nuclei at energy range (10-50) A MeV with <jats:sup>28</jats:sup>Si target is presented. The secondary beams of light nuclei were produced by bombardment of the <jats:sup>15</jats:sup>N (50 A MeV) primary beam on Be target and separated by COMBAS fragment-separator. In dispersive focal plane a horizontal slit defined the momentum acceptance as 1% and a wedge degrader of 600 μm Al was installed. The B<jats:sub>ρ</jats:sub> of the second section of the fragment-separator was adjusted for measurements in energy range (10-45) A MeV. The strong absorption model reproduces the A-dependence of ψ<jats:sub>R</jats:sub>, but not the detailed structure. We are comparing our experimental data with predictions of microscopic (dashed line) and strong absorption model, Glauber multiple scattering theory and preliminary results are obtained.</jats:p>
