✦ Synopsis

Aque& FeSO4.7HzO solutions of different con~ntratio~ were quickly f&en to liquid nitrogen temperature and the zero-w&city Mijssbauer transmission and differential thermodnalyticai (DTA) curves were measured simulta-,. '1 _ neousl~ tii the sani$les warmed uh. On the DTA cn&e& in exothermic peak codd be observed at asioui +60"C. Also :

.' changes in the Mtissbauer parameters were found io take place at this temperature..
