The nucleus 206Po was studied in the two proton transfer reaction Pb-204(O-16,C-14)206Po and the lifetime of the first excited 2+ state was determined by utilizing the Recoil Distance Doppler Shift method. The experimental results are compared with shell-model calculations based on different effective interactions. The calculations qualitatively reproduced the experimentally observed B (E2; 2(1)(+) -> 0(1)(+)) value, suggesting that the 2( 1)(+) state of Po-206 exhibits a collective nature. However, the employed effective interactions revealed some limitations, particularly in their description of the 4( 1,2)(+) states. These results emphasize the importance of understanding the properties of low-lying states, especially their evolution from single-particle dynamics to collective modes, in evaluating various effective nuclear interactions.

Abstract
The nucleus 206Po was studied in the two proton transfer reaction Pb-204(O-16,C-14)206Po and the lifetime of the first excited 2+ state was determined by utilizing the Recoil Distance Doppler Shift method. The experimental results are compared with shell-model calculations based on different effective interactions. The calculations qualitatively reproduced the experimentally observed B (E2; 2(1)(+) -> 0(1)(+)) value, suggesting that the 2( 1)(+) state of Po-206 exhibits a collective nature. However, the employed effective interactions revealed some limitations, particularly in their description of the 4( 1,2)(+) states. These results emphasize the importance of understanding the properties of low-lying states, especially their evolution from single-particle dynamics to collective modes, in evaluating various effective nuclear interactions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
