Excited K/sup. pi. / = 0/sup +/ rotational band in /sup 28/Si

An excited K/sup ..pi../ = 0/sup +/ band in /sup 28/Si which can be associated with the prolate Hartree-Fock solution has been observed in the /sup 25/Mg(..cap alpha..,n..gamma..) and /sup 27/Al(p,..gamma..) reactions. The I/sup ..pi../ = 0/sup +/ through 6/sup +/ band members have been located at E/sub x/ = 6691, 7381, 9164, and 11509 keV, respectively. Strong distortion is indicated from B(E2) values, resulting in Vertical BarQ/sub 0/Vertical Bar = 876/sup +110//sub -/85 mb.
