Experimental evidence for low-lying quadrupole isovector excitation of $$^{208}$$ 208 Po
The European Physical Journal A(2020)
摘要
We present the results from an experiment dedicated to measure the lifetime of the
$$2^+_2$$
state, candidate for the one-phonon mixed-symmetry state, of
$$^{208}$$
Po. This nucleus was studied in the
$$\alpha $$
-transfer reaction
$$^{204}$$
Pb(
$$^{12}$$
C,
$$^{8}$$
Be)
$$^{208}$$
Po and the lifetime of the
$$2^+_2$$
state was determined by utilizing the Doppler-shift attenuation method. The experimental data show that the
$$2^+_2$$
state decays with a sizable M1 transition to the
$$2^+_1$$
state revealing its isovector nature.
