چکیده
محاسبه واپاشی آلفای نیم‌عمر ایزوتوپ‌های Pt۱۶۶-۱۹۰ با استفاده از مدل گاموف- گونه (MGLM) و مدل پتانسیل وودز- ساکسون انجام شد. برای مشاهده اثر پتانسیل هسته‌ای تغییر یافته بر نیم‌عمرهای واپاشی- ایزوتوپ‌های پلاتین، پتانسیل وودز- ساکسون نیز به کار برده شد. با مقایسه با داده‌های تجربی، همه این مدل‌ها توصیف بسیار خوبی از نیمه عمرهای تجربی به دست می‌دهند.این مقایسه همچنین پیشنهاد می‌کند که نیم عمرهای محاسبه شده با در نظر گرفتن دگرگونی نسبت به نتایح به دست آمده با پیکربندی کروی، تطابق بهتری با داده‌های تجربی نشان می‌دهد. مقادیر کمیت جدید به دست آمده با مدل MGLM (نشان داده شده با MGLM2) به دست آمده است. مدل MGLM2 توصیف بهتری از نیم عمرها در مقایسه با MGML1 نشان می‌دهد

چکیده [English]
Calculations of the α-decay half-lives of Pt isotopes have been carried out using the modified Gamow-like model (MGLM) and deformed Woods-Saxon potential model. In order to see the effect of using deformed nuclear potential on the α-decay half-lives of the Platinum isotopes, the spherical Woods-Saxon potential has also been employed in the computation. When compared with experimental data, all the models
give very good descriptions of the experimental half-lives. The comparison also suggests that the calculated half-lives considering deformation give better agreement with the experimental data than the results using spherical configuration. New parameter values were obtained for the MGLM model (termed MGLM2). The MGLM2 model gives better descriptions of the half-lives than the MGLM1 model.
