Ефективний переріз збудження ізомерного стану ядра 115 In в реакції (γ,γ′)

On brake bunch of the betatron and the microtron of Department of Nuclear Physics of Uzhgorod National University is received curve of output to  115 In(γ,γ ′ ) 115m In reaction in interval of energy 7-25 МeV with at a walk 0,5-1 МeV. On got crooked output is calculated the efficient section of reaction. It is revealled that the second maximum exists at energy 22 МeV in efficient section of  115 In(γ,γ ′ ) 115m In reaction.
