Two proton and two neutron photoemission cross sections of {sup 63}Cu
- Laboratorio do Acelerador Linear, Instituto de Fisica, Universidade de Sao Paulo C.P. 66318, 05389-970 Sao Paulo, Sao Paulo (Brazil)
The ({ital e},2{ital p}) and ({ital e},2{ital n}) cross sections and the ({ital e}+{gamma},2{ital p}) and ({ital e}+{gamma},2{ital n}) yields have been measured for {sup 63}Cu in the electron energy range 28--60 MeV. The experimental results have been analyzed using distorted-wave Born approximation {ital E}1 and {ital E}2 virtual photon spectra in order to derive the {ital E}1 and isovector {ital E}2 components of the ({gamma},2{ital p}) and ({gamma},2{ital n}) cross sections. In the 2{ital n} channel the {ital E}1 component exhausts 12.4(11)% of the {ital E}1 energy weighted sum, while the isovector {ital E}2 component exhausts 52(15)% of its sum. The 2{ital p} channel exhausts 1.03(8)% of the energy weighted sum for {ital E}1 and we were able to establish an upper limit for the isovector {ital E}2 contribution of 0.58% of its sum.
