“…The change in K for all transitions is therefore Ai£=0, which usually results in more predictable intensity ratios for El transitions. 41 "" 45 Also, any mixing of the two negative-parity bands does not introduce a different value of K. Hence all parts of the wave function still correspond to i£= § and do not, therefore, lead to a change in the intensity ratios for transitions with single multipolarity.…”

“…same rotational band, but those for transitions to different rotational bands can differ by an order of magnitude or more. [42][43][44][45][46] This is especially true if some of the transitions are iT-forbidden.…”

Electromagnetic transition strengths in52109Te

“…The presence of these additional decays results from the increase in energy of the νh 11/2 level with respect to the lower 9/2 + orbits around the Fermi surface, as the N = 50 shell closure is approached. This, coupled with the systematic studies of E1 transition strengths by Lobner and Malmskog [51,52], highlighting the wide range of expected B(E1) values that result from the natural hindrance associated with E1 transitions undergoing a configuration change, precludes any comparison with previous measurements in the tellurium isotopes. Table V compares the experimental and theoretical excitation energies and reduced transition probabilities for the low-lying positive parity states in 109 Te.…”

“…They include early compilations of transition strengths in odd-A nuclei [20], odd-odd nuclei [21] and a range of odd-A, odd-odd and even-even isotopes [22]. Later studies, that incidentally do not examine the decay properties in detail, include the early work of Jain et al [23] on intrinsic states and their configurations in deformed nuclei in the range 60 < Z < 76 and 90 < N < 114; a series of studies [24][25][26][27] covering configurations, intrinsic states and associated rotational bands in even-even and odd-odd, medium-heavy and heavy nuclei; and a recent compilation by Singh et al [28] focused primarily on the properties of three-quasiparticle rotational bands and configurations in the A = 153-187 region.…”
