Nuclear structure effect on internal conversion ofl-forbidden transitions in139La,141Pr and203Tl

Penetration effects in the internal conversion process of the 204 keV transition in205Tl

“…Sizeable penetration effects have been detected in Z~ (2=4.0 [6]) and in 2~ (2=6.4 [7]). On the basis of the R,~ values also larger effects could be expected in 2~…”
