By using an ionisation instrument which records every one or two minutes it is possible to follow the variation of intensity of a radiation. We found that variations of gamma radiation were followed without any delay. On the contrary the variation of the intensity of cosmic radiation, by changing th

Gamma-ray spectroscopy holds great promise for probing nucleosynthesis in individual stellar explosions via short-lived radioactivity, and for measuring current global Galactic nucleosynthesis with longer-lived radioactivity. The former case was realized first for a Type II supernova when both 56Co
