| 摘 要： | 引入正弦平方势，在经典力学框架内，将面沟道粒子的运动方程化为标准的摆方程，并用Jacobian椭圆函数和椭圆积分解析地给出系统的解和粒子运动周期，导出了正电子面沟道辐射的瞬时辐射强度、平均辐射强度和辐射谱特征.结果表明，沟道辐射频率己进入γ-能区，并指出了利用它作为短波长激光的可能性.关键词：沟道辐射非线性正弦平方势

| Abstract: | The sine-squared potential is introduce to describe the interaction between particles and the crystal.The motion equation of the planar channelling particles is reduced to the pendulum equatione by this interaction potential.The solution of the equation and the period of the particle motion are expressed exactly by means of Jacobian elliptic function and elliptic integral.The radiation intensity and properties of the radiation spectrum are discussed.It is point out that it is possible to take channeling radiation as a new γ-Laser. |
