结果表明,OH 1720 MHz线可以强烈反转碰撞激发的旋转状态,优先的$sup 2$$pi$$sub 3$/$sub 2$阶梯。也有人认为,辐射泵(任何波长)可以强烈地只反转1612 MHz的线。在低OH密度(n/sub OH/10 $sup-3 $-10 $sup- 4$ cm$sup-3 $)下,用碰撞或辐射泵浦都可以实现垂直巴托垂直巴托近似小于1的1720 MHz谱线反转。(AIP)
It is shown that the OH 1720-MHz line can be strongly inverted by collisions which excite the rotation states, preferentially the $sup 2$$pi$$sub 3$/$sub 2$ ladder. It is also argued that radiative pumps (of any wavelength) can strongly invert only the 1612-MHz line. Inversion of the 1720-MHz line with vertical-bartauvertical-barapproximately-less-than1 can be achieved by either collisional or radiative pumps at low OH densities (n/sub OH/10$sup -3$-10$sup - 4$ cm$sup -3$).
