Evolution temporelle d'une population de noyau radioactifs

Equation de desinteraction radioactive dN(t)/dt = -L . N(t) derive proportionelle au noyaux restant le -L traduit une decroissance

Question 4
Question 2
Question 3
Question 1

N(t)= N0 / 2 => t1/2=ln(2) : L L= ln(2 )/ t1/2

Valeur de = 3.52x10E-3 Valeur de t1/2 = 197 secondes
