Proton halo çekirdeklerinde dış bremsstrahlung

$beta$ parçacıkları, yüklü bir madde içinden geçerken çarpışma yoluyla enerjilerini kaybederler. Kaybedilen enerjiye karşılık gelen ve elektronların yavaşlatilmasıyla üretilmiş olan elektromanyetik radyasyona, bremsstrahlung denir, $beta$-bozunumunda yayınlanan elektronun maksimum uç nokta enerjisi ile, dış bremsstrahlung spektrumundaki fotonların maksimum enerjisi birbirine eşittir. Bu çalışmada, bazı proton halo çekirdeklerinin, 8B, 9C, 12N, 17F, 17Ne, $beta$-bozunumuna eşlik eden dış bremsstrahlung spektrumlan hesaplanarak, Fermi-Kurie grafikleri elde edilmiş ve çekirdeklerin dış bremsstrahlung spektrumundaki fotonlann uç nokta enerjilerinin analizleri yapılarak, bunlar hakkında bilgi edinilmiştir.

The external bresstrahlung of proton halo nuclei

When the$beta$-particles pass through the charged matter they lose their energy by collisions and the radiation, emitted against loss of their energy is called bremsstrahlung since it is produced by slowing down of the electrons. The maximum end point energy of electrons, emitted in $beta$-decay is equal to the that's of photons in the external bremsstrahlung spectrum. in this study, the external bremsstrahlung spectrum accompanying $beta$-decay for some proton halo nuolei as 8B, 9C, 12N, 17F, 17Ne have been calculated and constructed the Fermi-Kurie-type plot of them. The significance of the reasonable approximation is primarily that it confirms our analysis of the external bremsstrahlung spectrum for proton halo nuclei and end point energy that have been recognised.
