Angular distributions of the 4He+Be elastic and inelastic scattering were measured at the energy Elab=63MeV, delivering by the K130 Cyclotron of the Jyväskylä University.
Angular dependences of the differential cross sections for the 4He(9Be,9Be*)4He, 4He(9Be,10Be)3He and 4He(9Be,10B)3H have been measured to get potential parameters.
Adding of second valence neutron or proton to the 9Be nucleus leads to the production of nuclei 10Be and 10B. As an example, differential cross sections versus angle for the ground states for 10Be and 10B are given in Figure. Results of the present experiment are shown by solid symbols and data from [1] are presented by the open symbols.

These reactions were used as an effective method to study the both internal cluster structures and isobar analog states for 10Be and 10B, as members of Jp=0+, T=1 multiplet. Experimental angular distributions for ground and for a few first excited states were analyzed with the frame of the optical model and distorted-wave theory DWUCK5 [2].
An attempt to extract spectroscopic factors was performed.
