INSTITUTE (1USABRK,1USAUCX) C229800100007
FACILITY (CYCLO,1USABRK) 60-inch cyclotron of the Crocker C229800100008
Laboratory. C229800100009
SAMPLE The target used for this work contained about 10**13 C229800100010
atoms of monoisotopic Cf249 in addition to about C229800100011
2x10**13 atoms of its parent Bk249. C229800100012
METHOD (CHSEP,REC,ACTIV) Immediately after bombardment, the C229800100013
californium and einsteinium reaction products were C229800100014
separated by ion-exchange methods and C229800100015
electrodeposited on platinum foil for examination by C229800100016
alpha pulse-height analysis. C229800100017
ANALYSIS The approximate cross sections were calculated from C229800100018
the observed alpha-disintegration rates and branching C229800100019
ratios, assuming recoil collection yields of 100% in C229800100020
the bombardments. C229800100021
