Polarizabilidades elétrica e magnética do próton

Polarizabilidades elétrica e magnética
Abstract in Portuguese
Estimamos os valores das polarizabilidades dipolares elétrica e magnética do próton, levando em conta as contribuições das ressonâncias nucleônicas de menor massa: P33 (1236), P11 (1450), D13 (1525), S11(1550), e da ressonância mesônica ε (660). O valor obtido para a soma das polarizabilidades concorda bem com os dados experimentais. Por outro lado, o valor obtido para cada uma delas, que depende do valor não bem determinado da largura do decaimento ε → Υ Υ, é compatível com os valores experimentais

Abstract in English
We have estimated the values of electric and magnetic polarizabilities of the proton, taking into account the contributions of the low masses nucleon ressonances : P33 (1236), P11 (1450), D13 (1525), S11(1550) and the meson ressonance ε (660). The obtained value for the sumo f the polarizabilities is in good agreement with the experimental data. On the other hand, the value, of each polarizability, which depends on the not too well determined width decay ε → Υ Υ, is compatible with experimental values
