Fragmentation of stretched spin strength in /sup 28/Si

Journal Article · · Phys. Rev. Lett.; (United States)
Calculations have been made to explore the effect of configuration mixing in a large basis on the fragmentation of the ''stretched'' M6 strength in /sup 28/Si. Our work extends a previous calculation, which allowed a single particle in the f/sub 7/2/ orbit and the remainder in the (unrestricted) 1d/sub 5/2/ and 2s/sub 1/2/ orbits, by also allowing up to four particles in the 1d/sub 3/2/ orbit. It is found that configuration mixing within this expanded basis gives an improved description of the spectrum and several other properties of the observed states.
