Shahab | Runs | Nice picture from 205-Tl |
In this high contrast Schottky recording, the main three frequency peaks are resolved w.r.t. time from left to right:
203 Hg 80 +, 200 Hg 79+ and 205 Tl 81+
There are also some spurs visible, whose nature is not 100% sure. One possible explanation can be:
Since this is taken during the storage time (gas target still off), we have no separation between parent and daughter ions, the daughter 205 Pb 81+ basically has the same revolution frequency as parent. It is a possibility that after the decay, daughter ions are slowly cooled back to the nominal frequency. Daughter ions are highly charged and have a high velocity, so single ion sensitivity is expected. They come from all directions, but Schottky measures only the longitudinal plane. Symmetric spurs can hence be an indication of this. |
