A088400100024 SAMPLE The Bk-249 was produced of seven targets, containing A088400100025 approx. 50 g of actinides, predominately Cm (42 g), A088400100026 Am (5 g) and Pu (3 g) A088400100027 Six targets were manufactured from this material, by A088400100028 depositing BkO(2) oxide onto 0.74 mg/cm**2 Ti foils to A088400100029 a thickness of 0.31 mg/cm**2 of Bk-249. Each target hadA088400100030 an area of 6.0 cm**2 in the shape of an arc segment A088400100031 with an angular extension of 60 deg and an average A088400100032 radius of 60 mm. A088400100033 In the course of the bombardment with an intense beam A088400100034 of Ca-48, the target layers of BkO(2) were A088400100035 systematically monitored by counting particles from theA088400100036 decay of Cf-249, the beta-decay daughter of Bk-249Bk. A088400100037 At the start of the experiment 37 mug/cm**2 of the A088400100038 Cf-249 daughter was present in the target.

The position-averaged detection efficiency for A088400100044 full-energy alpha-particles emitted in the decays of A088400100045 implanted nuclei was 87%.
