Abstract

We present results of derivations of neutron yields at the initiation of the nuclear reactions ⁹Be(gamma, n)2alpha and ¹⁸¹Та(gamma, n) ¹⁸⁰Та in the compound target consisting of the isotopes ⁹Be and ¹⁸¹Ta irradiated by the picosecond intense laser pulses. Gamma-radiation is appeared due to the Bremsstrahlung of relativistic electrons that are produced at the laser ponderomotive heating after multiple above-barrier laser ionization of target atoms. Theoretical calculations are in good agreement with the recent experimental data.

强激光引发光核反应9Be(γ,n)2 α时中子产额的计算

本文报道了由同位素9Be和181Ta组成的化合物靶在皮秒强激光脉冲照射下发生核反应9Be(gamma, n)2alpha和181Та（gamma, n） 180Та时中子产率的推导结果。伽玛辐射是由于靶原子经过多次势垒以上激光电离后，在激光重动力加热过程中产生的相对论性电子的轫致辐射而产生的。理论计算与最近的实验数据吻合得很好。
