CW and pulsed NMR experiments on 3He-4He mixture of 6.4 % at 0 bar have been made down to 0.53 mK. The absorption signals obtained by a cw NMR method under the field gradient show the existence of several spin wave modes. These spin wave modes are excited at the same time by an rf pulse. The absorption signals are very different from those of the previous results.
