通过改变电子储存环UVSOR-II上的激光和固定能量的电子束之间的碰撞角度，产生了能量可调的逆康普顿散射伽马射线。导出了γ射线能量和强度的解析表达式。在实验条件下，测量的γ射线能量和强度与理论值一致，脉冲宽度计算为几ps。结果表明，通过优化激光光斑的大小，可以产生脉宽为150 fs的超短γ射线脉冲。
Inverse Compton-scattered gamma rays of tunable energy were generated by changing the collision angle between a laser and an electron beam of fixed energy at the electron storage ring, UVSOR-II. Analytic expressions were derived for energy and intensity of the gamma rays. The measured energy and intensity of the gamma rays agreed with the theoretical values, and the pulse width was calculated to be a few ps, under experimental conditions. It was shown that ultra-short gamma ray pulses with a pulse width of 150fs can be generated by optimizing the size of the laser spot.
