Espalhamento Compton, Considere um raio X de comprimento de onda λ= 0,20 nm direcionado para investigar aspropriedades físico- químicas de um bloco...

O espalhamento Compton é um fenômeno em que um fóton de raio X colide com um elétron livre, transferindo parte de sua energia para o elétron e mudando sua direção. A mudança no comprimento de onda do raio X espalhado é dada por: Δλ = λ' - λ = h/mc * (1 - cosθ) Onde λ é o comprimento de onda do raio X incidente, λ' é o comprimento de onda do raio X espalhado, h é a constante de Planck, m é a massa do elétron, c é a velocidade da luz e θ é o ângulo de espalhamento. Substituindo os valores dados na fórmula, temos: Δλ = λ' - λ = (6,626 x 10^-34 J.s / (9,109 x 10^-31 kg) x 3 x 10^8 m/s) * (1 - cos30º) Δλ =
