Discovery of a 7.6-hour high-spin isomer of einsteinium-256

A 7.6-hour, beta-emitting isomer of /sup 256/Es has been produced via the (t, p) reaction by bombarding /sup 254g/Es with 16-MeV tritons. No evidence for an alpha branch has been found. A number of gamma rays have been observed, on the basis of which a partial decay scheme is proposed. It is conclud...

Sumario:A 7.6-hour, beta-emitting isomer of /sup 256/Es has been produced via the (t, p) reaction by bombarding /sup 254g/Es with 16-MeV tritons. No evidence for an alpha branch has been found. A number of gamma rays have been observed, on the basis of which a partial decay scheme is proposed. It is concluded that the isomer has spin 7 or 8. (2 refs).
