'die Ruhe' and 'die Besonnenheit' both have to do with calm behavior in difficult moments. 'Ruhe' mainly describes the inner state: you are not upset and remain calm. 'Besonnenheit' describes more strongly how someone acts: calmly, thoughtfully, and sensibly. So you can feel Ruhe and react with Besonnenheit.
