1966 W. V. Smith & P. P. Sorokin Laser vii. 369 The stage was nearly set for the actual achievement of an injection maser. The remaining question was: in what sort of a structure could masing action be achieved.
1972 Monthly Notices Royal Astron. Soc. Short Communications 160 27 p The increase in the values of the radial velocities of Orion A radio recombination lines with n may be explained in terms of masing and a radial expansion of the nebula.
1999 Monthly Notices Royal Astron. Soc. 302 1 Line emission is concentrated towards the 9 GHz continuum emission, and arises as a result of weak masing.

1972 Monthly Notices Royal Astron. Soc. 17 29 p The observer principally measures the velocity of the masing regions, the nebular gas furthest from the observer contributing very little to the line intensity.
1982 Sci. Amer. June 42/1 From Doppler shifts in the frequency of the maser radiation it is possible to measure the radial velocity of the ‘masing’ clouds.
