Öz

Bu çalışmada Pb izotoplarının (178A220)
alfa bozunum yarı-ömürleri, WKB (Wentzel-Kramers-Brillion) metodu, Sahu formülü
ve yakın zamanda önerilen New RenB formülü çerçevesinde hesaplanmıştır. Bu üç
model alfa bozunumları üzerindeki açısal momentumun (L) etkisini içermektedir.
Böylelikle farklı mekanizmalar arasında, her bir metot için hesaplanmış rms
değerleri kullanılarak karşılaştırmalarda yapılmıştır. Elde edilen sonuçlara
göre, nükleer yarıçap ifadesinde değişiklik yapılan Sahu formülünün alfa
bozunum yarı-ömürlerini tahmin etmede oldukça başarılı olmuştur. Bu çalışmada
elde edilen tahminler, olası deneysel araştırmaların önünü açabilir.
