Investigation of the elastic and inelastic scattering of ⁴He from ¹¹B in the energy range 29-50.5 MeV

We have measured the angular distributions for the elastic and inelastic scattering of ⁴He from ¹¹B in the isochronous cyclotron U-150 M INP RK. The extracted α-particles beam has been accelerated to energy 29 MeV and then directed to ¹¹B target. The experimental results were analyzed within the framework of both the optical model using different complex potential and the double folding potential obtained with different density-dependent NN interactions which give the corresponding values of the nuclear incompressibility K in the Hartree-Fock calculation of nuclear matter.
