The photoproduction of π
0-mesons from the nucleon and deuteron has been studied for incidents of photon energies up
to 1.5 GeV. By using the MAID-2007 model for the process on the nucleon, we predict results for the unpolarized and
helicity-dependent total cross sections of the semi-exclusive reaction γd→π
0X (X=np+d) with the inclusion of
rescattering effects. We find that rescattering effects yield a substantially large contribution. The extracted results are
compared with the available experimental data and a satisfactory agreement is obtained. In addition, the contribution of
γd→π
0X (X=np+d) to the finite GDH integral has been evaluated by explicit integration up to 1.5 GeV and a total value
of 256.96 μb has been obtained. Convergence of the GDH integral has been reached.
Fotoproduksi Meson-π0 dari Nukleon dan Deuteron. Fotoproduksi meson-π
0 dari nukleon dan deuteron telah dipelajari
untuk energi-energi foton datang hingga 1.5 GeV. Dengan menggunakan model MAID-2007 untuk proses produksi
pada nukleon, kami meramalkan hasil-hasil perhitungan penampang lintang total tidak-terpolarisasi dan penampang
lintang total bergantung-helisitas dari reaksi semi-eksklusif γd→π
0X (X=np+d) dengan memasukkan efek rescattering.
Hasil studi memperlihatkan bahwa efek rescattering memberikan kontribusi sangat besar. Perbandingan hasil-hasil
ekstraksi dengan data eksperimen yang tersedia memperlihatkan kecocokan yang memuaskan. Sebagai tambahan,
kontribusi dari proses γd→π
0X (X=np+d) pada integral GDH berhingga telah dihitung dengan menggunakan integrasi
eksplisit hingga 1.5 GeV dan nilai total sebesar 256.96 μb telah diperoleh. Konvergensi dari integral GDH telah tercapai.
