Investigations on Radioactivity of 141–229 Tm

We explored one and two proton radioactivity in 141–229 Tm nucleus isotopes. An effective liquid drop model is used to calculate the proton decay half-lives. The WKB integral is used to calculate the penetration probability. The half-lives of one and two proton radioactivity are compared to those of β ^± and α decay. Furthermore, proton-decay, beta-decay, and alpha-decay half-lives are compared to experimental results. The result derived from the current investigation is consistent with previous experimental data. Further, we have identified potential proton emitters and β ^- emitters in the unexplored regions of mass number range 141≤ Z≤ 146 and 48 β ^- -emitters in the mass number range 182≤ Z ≤ 229 for Thulium nuclei. The existence of positive Q values for these isotopes was estimated through theoretical calculations, as experimental data on mass excesses in these regions are currently unavailable. These newly found isotopes have potential use in medical imaging, treatment of cancer, dosimetric studies, and radio-guided surgery.
