This paper reports on mass separated sources of {sup 225}Th used to study the level structure of {sup 221}Ra following alpha decay. Fluorination techniques were used to obtain the selectivity in atomic number. The low lying levels in {sup 221}Ra are interpreted in terms of K = 5/2 {sup {plus minus}} and 3/2{sup {plus minus}} parity doublet bands which occur naturally from reflection asymmetric models. The anomalous spin sequences in the K = 3/2{sup {plus minus}} bands of {sup 221}Ra are interpreted in terms of their Coriolis coupling with K = 1/2{sup {plus minus}} bands with large decoupling parameters. The low-lying parity doublet bands in {sup 221}Ra, {sup 223}Ra and {sup 225}Ra, and particularly the Coriolis coupling of their K = 3/2{sup {plus minus}} bands, are compared and contrasted.
