摘要

【正】 The angular distributions,excitation functions and absolute cross sections of a parti-cles from p-¹¹B reaction for proton energies from 778 keV to 3389 keV are measured.The PIPS（Passivated Implanted Planar Silicon）and ΔE detector spectrometer is used to distinguish theprotons and α particles based on the fact that proton peak has larger displacement when protonspass through the ΔE detector.Whole spectra of ¹¹B（p,2α）⁴He subsequential decay via the firstexcited state of ⁸Be are first measured.The behavior of the cross section is discussed.
