Reactions of 14C beams on targets of 14C and 10Be have led to new insights into the structure of several hard-to-produce nuclei in the s-d shell. Particle coincidences were essential to observing gamma lines in the most neutron-rich reaction products. The rich decay scheme observed in 27Na provides the first gamma decay scheme of a T = 5/2 nucleus in the s-d shell and permits careful tests of models such as the USD shell model. The level scheme of T = 2 24Ne has been greatly expanded compared to earlier (t,pg) studies, leading to a better understanding of the variation of shell gaps with neutron number. A newly-observed low-lying intruder state in T = 2 22F provides new insights into the cross shell interactions.
