Half-lives of 2{sub 1}{sup +} levels (2.80(8) ns in {sup 98}Sr, 0.55(2) ns in {sup 100}Zr) and the {sup 98}Sr 4{sub 1}{sup +} level (80(6) ps) were obtained using a {beta}-{gamma}-{gamma} triple coincidence system. Analysis of B(E2) and B(E0) rates indicates that {sup 98}Sr and {sup 100}Zr have very similar structures. Both have a highly deformed ({beta} {approx equal} 0.4) yrast band and a moderately deformed (vertical stroke{beta}vertical stroke {approx equal} 0.2) low-lying band. The highly deformed bands in {sup 98}Sr and {sup 100}Zr are nearly identical to the yrast bands in {sup 100}Sr and {sup 102}Zr. (orig.).
