Systematic study of proton radioactivity of spherical proton emitters within various versions of proximity potential formalisms [PDF]
European Physical Journal A, 2019 In this work we present a systematic study of the proton radioactivity half-lives of spherical proton emitters within the Coulomb and proximity potential model. We investigate 28 different versions of the proximity potential formalisms developed for the description of proton radioactivity, $\mathcal{\alpha}$ decay and heavy particle radioactivity.

Subarctic-scale transport of 134Cs to ocean surface off northeastern Japan in 2020
Scientific Reports, 2023 We studied the spatiotemporal variations in 134Cs, 137Cs, and 228Ra concentrations at the sea surface off southeastern Hokkaido, Japan (off-Doto region) from 2018 to 2022 using low-background γ-spectrometry.
