Sažetak
9Be(3He, n)1 1C, 9Be(3He, nγ)1 1C, 9Be(3He, pγ)1 1B and 9He(3Be, p)1 1B reactions are studied, at 5OO keV < E3H0 < 1100 keV, in an attempt to obtain the additional data on 26. 9 MeV level of 1 2C. The absence of any resonant behaviour at excitations corresponding to 26. 9 MeV in 1 2 C system is interpreted as a case of J forbidness of compound nucleus mechanism, Jir being limited to 0 - , 3 - and 4 - for this state. This forbidness inaugurates the direct mechanisms to be dominant even at low energy, as seen from the fits of experimental data.
