The ion density of large ions varies widely, depending upon the degree of atmospheric pollution. Representative low-altitude values might be 1000 per cubic centimeter in clean country air, 10,000 per cubic centimeter in an industrial area, and 100 per cubic centimeter over the oceans. 1, record 1, English, - large%20ion

Ces noyaux de condensation comprennent d'une part des «noyaux neutres» - poussières d'origines diverses [...] qui sont surtout abondants dans les deux ou trois premiers kilomètres de l'atmosphère, et d'autre part des particules électrisées, les ions, présents partout, qui s'unissent aux noyaux neutres pour former des «gros ions». Le rôle des gros ions est capital dans la condensation et par voie de conséquence dans les précipitations. 1, record 1, French, - gros%20ion

Grâce aux faisceaux d'ions lourds stables accélérés par deux cyclotrons du GANIL à une énergie de 50 à 100 méga-électrons-volts par nucléon, la collision des ions-projectiles (ions primaires) avec le noyau cible fragmente le projectile en produisant des ions secondaires, émis vers l'avant dans un cône. 2, record 2, French, - ion%20lourd
