                            <p>Bu çalışmada Slater Tipi Orbitaller (STO) ve Gauss Tipi Orbitaller (GTO) kullanılarak Li (Lityum), Na(Sodyum) ve N (Azot) atomlarında, elektrik dipol yaklaşıklığı altında ilk uyarılmış seviyeden temelseviyeye kendiliğinden geçiş olasılıkları hesaplanmıştır. STO baz setleri kullanılarak gerçekleştirilenhesaplamalarda, öncelikle tek elektronlu atom yaklaşımı altında kendiliğinden geçiş olasılıkları içinanalitik ifadelerin türetilmiştir. Daha sonra bu analitik ifadeler çok elektronlu atomlara genişletilse de STObaz setleri kullanılan hesaplamalarda elektronlar arası LS çiftlenimleri ve konfigürasyon etkileşmelerihesaba katılmamıştır. Elde edilen nihai ifadeler kullanılarak geçiş olasılıkları hesabı için C bilgisayarprogramlama dilinde bir bilgisayar programı yazılmıştır. Yazılan bu program sayesinde STO baz setlerininkullanıldığı hesaplamalar gerçekleştirilmiştir. Ayrıca aynı hesaplamalar GTO baz setlerini kullananGaussian 98 paket programı yardıPı ile tekrarlanmıştır. Fakat bu hesaplamalar esnasında Gaussian 98paket programında tekli yerleşim etkileşmelerini hesaba katan CIS hesaplama yöntemi seçilerek birnebzede olsa yerleşim etkileşmeleri hesaba katılmıştır. STO ve GTO baz setleri kullanılarak elde edilensonuçları birbirleriyle ve literatürdeki mevcut sonuçlarla karşılaştıUılmıştır. Bu sonuçlar ışığında çeşitlihesaplama teknikleri ve farklı baz setleri kullanılması arasındaki farklar tartışılmıştır.</p></trans-abstract>

For the calculationsbased on STO type orbitals analytic expressions were obtained for the spontaneous transition probabilitieswithin the single electron atom approximation. Although obtained analytical expressions were extended toinclude many electron atoms, LS coupling among electrons and configuration interaction effects were nottaken into consideration. A computer program was written in C programming language by using theseanalytical expressions and the calculations for STO type orbitals were performed by using this program.Also similar calculations were performed using the Gaussian-98 software in which GTO basis functions areemployed. However, in the calculations with Gaussian-98 we have used CIS method which takes singleconfiguration interactions into account. The results obtained from the calculations with STO and GTO basissets were compared with each other and the values obtained from the literature. Considering these results,the differences between different calculation methods and different basis sets were discussed.</p></abstract>
