Abstract
In shell model calculations for the yrast even spin states of 50Cr, the static quadrupole moments of the low spin states 2+_1 and 4+_1 are negative but those of the high spin states 10+_1, 12+_1 and 14+_1 are positive. Even spin states beyond the single j shell limit, J_max=14, again have negative moments. While the B(E2)'s for the J -> J-2 transitions are strongest along the yrast path for J <= 8, it is found that the transition from the second J=10 state to the first J=8 state (10+_2 -> 8+_1) is much stronger than the 10+_1 -> 8+_1 transition. We also note that while the 16+_1 -> 14+_1 transition is weak, the 16+_1 -> 14+_2 is quite strong.
