Energy levels of 28Si

Coupled-Channels Analysis of Nucleon Interaction Data of28'30Si up to 200 MeV Based on the Soft Rotator Model

“…|β 2 | 2 + 1 , is 0.475, which can be compared with the value of β 2 = 0.407 determined from B(E2) ↑ recommended by Raman et al 39 41,42) However, it is consistent with β 3 =0.320 determined by analyzing the proton scattering experiment, 17) and the latter is in much better agreement with our value.…”

The structure of28Si above 10 MeV excitation energy II: Assignments of quantum numbers

“…Table 5 contains a few changes in spin assignments/restrictions as compared to the literature. Meyer et al [12] report I ~ = 2 + assignments to the 12916 and 12923keV levels. They are strong resonances of the 27Al(p, 7) reaction with similar 7-decay modes so that they could constitute a pair of mixed T = 1 + 0 states.…”

“…In the latter cases they follow from the results of the subsequent Tables 3, 4 independent of the content of the present table a The recommended Table 5 we establish a T = 1 character of the initial state independent of its spin assignment. Hence the upper limit of 5 W u applies m The level is a 24Mg(:~, 7) resonance [9] nThe branching ratios for 7-decay are given in [12]. Very weak branches to I n = 0 + states are considered as unsafe and discarded here ~ Ref.…”

“…To extend the efficiency determination to higher energies, we measured the 27 Al(p, γ) reaction using a thick aluminum target and used the relative intensities of well-known gamma-ray branches from E p = 633 and 992 [41,42]. For the latter resonance, our coin target was also used.…”
