Abstract：
The p-h calculation of 1 ^-states and its E1transition probabilities in Pb ²⁰⁸ismade with different types of two-body forces. The same, calculation is made for Hg ²⁰⁰,Pt ¹⁹⁴, W ¹⁸⁴using BCS wave function as basis vectors. The agreement between ob-servation and calculation is quite well in the general trend. In addition the calcu-lations demonstrate the de-coupling of E1transitions of low l-configurations fromthe giant dipole resonance, the spin-isospin oscillation at lower energy and the effectof spin-orbit coupling force on the pygmy resonance.
