Simultaneous observation of NMR spin noise and maser spontaneous emission

- Narrow maser peaks can be separated out of broad overlapped resonances.
- Spin noise dip, emission and spontaneous maser emission have been observed.
- Inverted magnetization produces maser emission and spin noise emission.
- Intensity of maser emission shows random behavior depending on gradient length.
- Scattering range of intensity varies with gradient length.
