Аннотация:
Measurements of the total reaction cross sections (σ<sub>R</sub>) for some proton-rich nuclei (N = 11-15 isotones) on a carbon target at intermediate energies have been performed on the Radioactive Ion Beam Line of the Heavy Ion Research Facility in Lanzhou. A larger enhancement of σ<sub>R</sub> for <sup>27</sup>P has been observed than for its neighbours. Evidence for a proton halo in <sup>27</sup>P has been revealed in the Glauber analysis of the total reaction cross sections in terms of the difference factor d.
