Occhialini’s scientific production between the two English periods

Occhialini’s scientific production between his stay at the Cavendish Laboratory in Cambridge in the early’ 30s and his stay at the Wills Laboratory in Bristol in the mid’ 40s is maybe the less known. The recollection of his papers was at the base of a reconstruction of his scientific activity and showed his work in a standard kind of researches on radioactivity and cosmic rays by means mainly of G-M counters and Wilson chambers(1), showing a status of continuity with his precedent activity in Florence and Cambridge. It was a particularly striking fact to note Occhialini’s technical ability in designing new kinds of simple devices to detect cosmic radiation in a situation of scarce financial and technological support.
