“…As a result, the nuclear potential depth is an important parameter to be considered in the cluster decay half-life calculations. For the alpha decay, the preformation factor takes the values between P α = 0.35 and P α = 1.0 in literature [59,60]. In the cluster decay calculations, we consider the preformation factor as follows [61],…”

We examine the alpha and heavier cluster decay half-lives of the nuclei for 87≤Z≤96 using the analytical formula obtained by the Wentzel-Kramers-Brilliouin (WKB) method within the framework of the cluster model for the modiﬁed harmonic oscillator and spherical Coulomb potential. We correlate the clustering eﬀect in the nuclei with the nuclear potential depth only and systematically investigate the alpha and heavier cluster decay half-lives. In addition to half-lives, the branching ratios relative to alpha decay half-lives are also calculated and results are compared with experimental data. The rms deviations of the alpha and cluster decay half-lives show a good agreement with the universal decay law (UDL), Horoi, and one single line of universal (UNIV) curve models. Utilizing the optimized cluster model parameters, we also predict the half-lives of 14C, 20O, 24,25Ne, 28,30Mg, and 32Si cluster emissions from various isotopes for guiding future experiments.

“…WKB metodu ile Schrödinger dalga denklemi seriye açılarak yaklaşık çözümler elde edilir (Miller ve Good, 1953). WKB nükleer reaksiyonların tesir kesitleri, bozunum genişlikleri, yarı ömür hesaplamaları gibi gözlenirleri elde etmede başvurulan yöntemlerden bir tanesidir (Soylu vd., 2018;Soylu, 2017;Koyuncu vd., 2017;Denisov ve Pilipenko, 2012). İkili kümelenme modeline göre etkileşime giren iki çekirdek arasındaki etkin potansiyel…”

Bu çalışmada Pb izotoplarının (178  A  220) alfa bozunum yarı-ömürleri, Wentzel-Kramers-Brillion (WKB) metodu, Sahu vd. (2013) formülü ve yakın zamanda önerilen New RenB formülü çerçevesinde incelenmiştir. Bu üç model alfa bozunumları üzerindeki açısal momentum (L) etkisini içermektedir. Böylelikle farklı mekanizmalar arasında, her bir metot için hesaplanmış rms değerleri kullanılarak karşılaştırmalar da yapılmıştır. Elde edilen sonuçlara göre, değiştirilmiş nükleer yarıçap ifadesine sahip Sahu vd. (2013) formülü, alfa bozunum yarı-ömürlerini açıklamakta oldukça başarılı olmuştur. Bu çalışmada Pb izotoplarının alfa bozunum yarı ömürleri hakkında elde edilen tahminler muhtemel deneysel araştırmalara rehberlik edebilir.

In this study, microscopic nucleon–nucleon Double Folding (DF) and phenomenological potentials have been used to investigate [Formula: see text]Ca reaction observables at sub-barrier energies. In the calculations, semi-classical Wentzel–Kramers–Brillouin (WKB) approach has been used in order to obtain the cross-sections and reaction rates of [Formula: see text]Ca. Besides WKB approximation, we have also utilized Talys code in order to get the comparative results and find out the method differences. To estimate the reaction rates, energy-dependent cross-sections and astrophysical S-factors of [Formula: see text]+[Formula: see text]Ca have been used. Herewith, differences between models and potentials have been demonstrated using the reaction rate estimates.
