TL;DR: In this article, the half-life of the first excited state in 207 Pb at 569.6 keV was measured to be (129±3) ps in excellent agreement with Weisskopf's single particle estimate of 128 ps for an E2 transition.

TL;DR: The linear polarizations of /sup 64/Zn..gamma.. rays, produced in the /sup 59/Co(/sup 7/Li,2n) reaction with E/sub 7Li/ = 18 MeV, have been measured with a Ge(Li) two-crystal Compton polarimeter as mentioned in this paper.
Abstract: The linear polarizations of /sup 64/Zn ..gamma.. rays, produced in the /sup 59/Co(/sup 7/Li,2n) reaction with E/sub 7Li/ = 18 MeV, have been measured with a Ge(Li) two-crystal Compton polarimeter. These polarization values were used with previously obtained ..gamma..-ray angular distribution measurements to make unique parity assignments for several states. The 641- and 1619-keV ..gamma.. rays have been found to be predominantly E1 transitions, and odd parity has been assigned to the levels at 2999 keV (3/sup -/), 3925 keV (5/sup -/), 4635 keV (7/sup -/), 4981 keV (7/sup -/), and 5681 keV (8/sup -/). Even parity assignments have been confirmed for levels at 991 keV (2/sup +/), 2736 keV (4/sup +/), 3994 keV (6/sup +/), and 4237 keV (6/sup +/). Also, the spin assignments for levels at 2307 keV (4/sup +/) and 4635 keV (7/sup -/) have been confirmed.
