球形质子发射体半衰期的微观计算

Microscopic calculation of half lives of spherical proton emitters

Madhubrata Bhattacharya, G. Gangopadhyay

摘要:

核中质子放射性的半衰期值已在WKB近似下计算。用两个微观NN相互作用DDM 3 Y和JLM折叠子核密度,得到微观质子-核势。密度已获得的相对论平均场方法在球近似使用力FSU金。如果采用其他共同力,则没有观察到结果的实质性修改。对几乎所有核的基态或低激发态衰变的计算结果都与实验测量符合得很好。讨论了少数情况下出现大偏差的原因。在$^{109}$ I和$^{112,113}$ Cs中的结果表明,与早期的计算相反,变形的影响很小。在两个原子核$^{93}$ Ag和$^{97}$ In中预测了可能的质子放射性。

英文摘要:

Half life values for proton radioactivity in nuclei have been calculated in the WKB approximation. The microscopic proton-nucleus potential has been obtained by folding the densities of daughter nuclei with two microscopic NN interactions, DDM3Y and JLM. The densities have been obtained in the Relativistic Mean Field approach in the spherical approximation using the force FSU Gold. No substantial modification of results has been observed if other common forces are employed. The calculated results for the decays from the ground state or the low-lying excited states in almost all the nuclei agree well with experimental measurements. Reasons for large deviations in a few cases have been discussed. Results in $^{109}$I and $^{112,113}$Cs show that the effect of deformation is small contrary to earlier calculations. Predictions for possible proton radioactivity have been made in two nuclei, $^{93}$Ag and $^{97}$In.
