Transcribed Image Text:5 For each of the following transitions, indicate if the transition is allowed. If not allowed
briefly explain why.
(a) 5f Fr→ 3d ³Dsz
(b) 1s 2s 2p 2Ds2→ 1s² 2s²2p³ S32
(c) 1s² 2s 2p ³p,→ 1s² 2s²2p¹ ³P₂
It is believed that the inter-nucleon force is repulsive at short range and is mediated by p
and a mesons. If their range is about 0.5 fm then estimate the mass energy in MeV of
these particles, stating your method.
